While text written on typewriters in the United States traditionally had two spaces between sentences, this is becoming less common and many sources now recommend having only one space, although this topic is still controversial.
This is particularly useful when plain text files based on a markup language (such as HTML, TeX, or Wiki markup) are edited by multiple people using a version control system where it helps to facilitate comparison of changes and avoid merge conflicts.
In most markup languages, a single linefeed in the source is rendered as a simple space, while two linefeeds generate a paragraph break.
This approach allows the source to be easily manipulated and versioned, while the rendered output still keeps the regular flow and justification abilities of running text.
The title text uses single spaces between the back-and-forth quotations; but within each quotation, the quoted speaker's preferred spacing is used.
In particular, when the single-spacing advocate claims to be using double spacing, this is indeed a lie.
Randall's mocking characterization in the title text of overzealous advocates using the phrase "WAKE UP, SHEEPLE" has appeared in previous comics 496: Secretary: Part 3 and 1013: Wake Up Sheeple.
One line per sentence is reminiscent of a diagrammed/formal logic argument in philosophy. It would be a much more effective convention to help people parse and interpret content and validity of e.g. political claims. 18.104.22.168 17:21, 2 November 2013 (UTC)

Writing plaintext, I always do two s after a sentence ending period.
This is probably because I did in fact start typing on a real typewriter.
In an environment where automatic formatting will take place, like a web page or wiki text, I use the newline.
I have had people in this wiki collapse my multiple line forms to one of the others.
(I was disappointed.)

I prefer double spacing, but I used single spacing in writing the explanation, just to make people happy. Perhaps I should have used new lines. Concomitant (talk) 05:10, 1 November 2013 (UTC)

The 'third way' is a little underappreciated here: it divides the text into self contained logical units, and makes text processing tools (grep, diff etc.) much more usable.
Proper text rendering engines (TeX, HTML, etc.) already make this assumption and group sentences accordingly.
If only I realized this earlier, it would have made my thesis revisions much more easier.
In fact, up to this moment, I thought I was that lone guy in the comic.

- As a programmer, I find nothing weird in adapting your style to language. Writing two s in HTML or TeX is useless, as they won't render as two s anyway. (While using for this purpose nonbreakable s, which would render, is a crime.) -- Hkmaly (talk) 10:48, 1 November 2013 (UTC)
- It would also render incorrectly if the period was close to the end of a line. If the markup is [last word of sentence][period][nbsp][next sentence], the last word of the first sentence could end up on the next line unnecessarily. But if it's [last word of sentence][period][nbsp][next sentence], the next line of text would start with a , which is much worse.--Rael (talk) 15:16, 1 November 2013 (UTC)
- I end my sentences with a line break, a % and another linebreak. Only after commata etc i use a single line break. Oh, and don't forget to protect the after points used in abbreviations, not as full stops, by a backslash. Most TeX increase the length of the after a full stop a bit. Bit question: Why don't double people, when using Word not just use a longer instead of a double . Noone would have the idea to indent a paragraph or substitute a tab with a series of s.188.8.131.52 03:11, 2 November 2013 (UTC)

So, why did double spacing after a period ever exist? It doesn't seem necessary. PheagleAdler (talk) 07:31, 1 November 2013 (UTC)
- Here's the standard explanation: on typewriters, each character takes up the same amount of . So a lower-case "i" takes up the same amount of as a capital "M". This is called a monospace font. When typing, if you just put a single after the end of period ending a sentence, the reader doesn't necessarily get the sense that a new sentence has started. This is particularly true if you were typing in all caps, as might be common on some types of forms or documents. Two s, however, does the job nicely. In theory, with modern proportional-width fonts, this is unnecessary. Rylon (talk) 23:36, 1 November 2013 (UTC)
- Here's the researched explanation: http://www.heracliteanriver.com/?p=324 So technically, an em- after a period, an en- after a comma. Or you know, whatever you want. 22.214.171.124 06:22, 17 July 2015 (UTC)
even though i learned typing on a typewriter, to this day i had never heard of the double thing. maybe it's a US only thing, like the stupid french with s BEFORE punctuation marks. Peter (talk) 07:54, 1 November 2013 (UTC)
- I've always taken the double- thing as a US thing. Some editors like emacs default to it, which is really annoying. That said, as a frenchman, the " before punctuation" is normal to me and it is part of the codified typography -- and I think this is actually an important distinction to make. Is this double- vs single- something codified somehow? As a last word, I need to be nitpicky: the exact French typography rule is "a before punctuation made of two parts (namely colon, semi-colon, exclamation/question mark) and no before punctuation made of a single part (dots, commas.)" It's a very deterministic rule that is easy to apply (whether one agrees to it or not.) Ralfoide (talk) 16:40, 1 November 2013 (UTC)
- This is a common question from the French and some other nationals. The answer is that English does not work that way. There is no official codified version. The most you have is small pockets of codification within an organization, such as The University of Boulder, or UPI or the US Army. If you're working in or with such an organization you should use their standard. If you try to extend any such standard to the rest of the world you are a nasty egomanical control freak who should be chopped into pieces and fed to the fishes.--126.96.36.199 18:25, 4 November 2013 (UTC)
As a german typographer I have to say I’m shocked! Two s per period? A before punctuation?! My scientific opinion: you all are completely crazy ;-) (Just kidding, but seriously, two s? In Germany, the first possibility to do that safely is your last will …) Quoti (talk) 10:34, 1 November 2013 (UTC)

As a(n automatic) two-spacer person (just you watch, I'll use 'em here, despite it obviously not being rendered), it's just what I learnt, back in the '70s, here in the UK. I've no idea why I learnt it. However, it may stem from the same root as the 'rule' in handwriting (not biros, but nibbed pens dipped in ink... wow, I feel old, but it was at primary school) that we use a gap as big as our our (very little) little-fingers to separate sentences. I imagine differentiating full-stops (US: periods) from commas in the messy medium of ink might be a valuable visual indicator as to what a given smudge might actually be. So, anyway, double-spacing. On the other hand I should report that, "I've dropped the habit it of appropriate punctuation prior to quotes," I say, "despite being the way I learnt it." And instead I will drop "<- Commas from that sort of position," you see, "even through I'll keep the ones that are semantic pauses." You see how my standards are slipping? Anyway, good comic.

- I'm in the same boat this this bloke. I don't get the typewriter tie in. I seem to recall being taught to use a finger gage correct gap of whitespace to leave between the end of one sentence and the beginning of the next. This was in an American small town southern school in the early 1980s. I assume it was for readability. 220.127.116.11 16:16, 1 November 2013 (UTC)

There's a FOURTH way! I receive a "Weekly Update from Tim Scott" HTML formatted about once a week (unsurprisingly) which, in lieu of s between words, uses a carriage return and a linefeed. This alleviates the question of how many s between sentences completely! It also renders as oneverylongword in my client. Ie:

I think the finger was to help kids create clear separation while developing their proficiency at penmanship.
I think the 2x is a fall out from the fixed width formatting of typewriters to help assist the reader (or proof reader) with the start and end of a sentence.
Double spacing has almost become OCD for me. I can't help it. Of course I also leave paragraph marks on while I type as well. I wonder if the French would require a before a double quote, "The author ponders. "
I think we could improve old school cryptography if we just used carriage returns and ignored the 'new' line.
I might be able to accept and adopt the single rule if I can make my s default to twice the point size of every other character in the style.

I'm not from the US so I never actually heard about a rule with two s. From my point of view the rule is stupid, really dumb. Just let go of it! There is no reason for it.

The 2 s used in (early) PCs and TypeWriters (and TTYs) could be caused by the too little difference between a «.» and a «,» with little fonts on CRTs (320*200px with 8*8px single letter with <16" monitors with a signal trought an RF cable, for a C64), dot-printers (like 60*75 dpi (h*v), 9*9 per character, for an Epson MX-80) and typewritten sheets (maybe with dirty sort/type)?
