You don't even have to be an extrovert to be bored by what passes for culture in "geek" circles.

A few examples might make your comment's disdain less grating.

Mindlessly repeating internet memes for one (except in Soviet Russia, where meme repeats you). That's at least 50% of internet humor. Obscure references, as well. It's a type of humor that makes no sense unless you're immersed in the culture.

And even when it makes sense it can be pretty damned tedious. (Of course, for the "joke" to be anything other than self-indulgent the reference can't be all that obscure, so what's the point?)

The convergence of "geek culture" and "internet culture" is one of my big complaints. lolcats were funny for about 5 minutes.

I didn't mean it as an attack, after all there is no accounting for taste.

Unless you like XKCD, in which case you are a bad person and you should feel bad.
