I've checked the network tab and console - nothing really seems to happen when you vote, which may be something we want to put on the explanation tomorrow - Myxoh
I suspect the real april fools joke is going to come on Wednesday when xkdc posts an app showing us our psychological profiles that they are now selling to marketing companies after data-mining our emotional preferences to marketing firms - Nosajimiki
@Nosajimiki: psychological profiles of xkcd fans. That might be some interesting marketing. - 5Cincinatus
@Myxoh: I came here to see if anyone else had noticed this! But, I do also see a websocket connection to emojidome.xkcd.com, I bet it's counting votes that way.
There is a websocket connection. A message is sent every time you vote. It looks like there are also status update messages every second (saying which emoji currently has exactly how many votes, i suspect this changes the amount of hearts that show up), and "bracket start" messages every so often. The bracket start message seems to contain hundreds of upcoming emoji pairs. Edit: a bracket start is sent at the start of every match (so every ~30 seconds). It also contains logs of which messages to show for previous matches, and which emoji are currently battling.18.104.22.168 16:30, 1 April 2019 (UTC)
There seems to be nothing stopping me from clicking multiple times. Do you think it actually counts it all those times? Can I click-spam to say "this is much better"? Fabian42 (talk) 16:48, 1 April 2019 (UTC)
Well this is fun. Look like there are 512 symbols, meaning 256 first-round contests. The first round would take (at 38 seconds / round) ~2.7 hours. The remaining rounds, from an estimate of geometric progression, would just under double this, meaning this comic will run for ~ 5 hours until we have our winner... ~alexandicity 22.214.171.124 16:51, 1 April 2019 (UTC)
