Title text: 'I was pretty good at skeet shooting, but was eventually kicked off the range for catching the clay pigeons in a net and dispatching them execution-style.'
The conversation in the first three panels is fairly banal—it's a quick rumination on the nature of social networking platforms, and a brief reflection on their evolution. Whether or not everybody switches over to Google+ or stays on Facebook is of no matter, as evidenced by the fact that AOL and IRC still both have devoted (if dwindling) followings.
And then, Black Hat shoots a crossbow bolt through the basketball.
It's a symbolic gesture. When Black Hat says he's not the 'catch' type, what we're really meant to take away from the comic is that Black Hat will do what he wants to do, regardless of what his friends are doing. They're shooting hoops, he's on his phone. They're playing catch, he's got a crossbow.
The point is that Black Hat doesn't care about universal acceptance. Black Hat cares about Black Hat. The fact that he's not the catch type symbolizes that while statisticians may portray social network-ers as a sort of hive mind that will gravitate towards one platform over another, at the end of the day that hive mind is made up of innumerable individuals, many of whom will share Black Hat's easily summarized world view: My way.
In the image text, we hear of another instance of him playing by his own rules at a skeet shooting range. A clay pigeon is a clay disc that is thrown into the air and serves as a target for a shotgun. The image text is a play on words, implying that the clay pigeons are the same as real pigeons, and Black Hat has captured them using a net and shot them from a very close range--completely unnecessary given that they are inanimate objects. It is especially surprising that Black Hat would bother to do this at all, especially since he has already proven himself to be an excellent shot.

- Cueball: Do you seriously think everyone will move to Plus? It was hard enough getting them on Facebook.
- [Friend attempts to throw the basketball through the hoop, but it bounces off.]
- Friend: Do they have to?
- Friend: My mom still uses AOL—it doesn't mean my social life has to happen there.
- [Cueball passes the basketball back to #2.]
- Friend: Universal adoption isn't everything. I mean, IRC is still—

- [An arrow pierces the ball.]
- [Black Hat has a one handed crossbow, and is still looking at a phone.]
- Friend: You're not really the "catch" type, are you?
- Black Hat: I am not.
