Yes, I'm being serious. I was thinking about posting at the Penny Arcade forums, but I went to their general chat forum and realized I would never be able to get into it.
Look at the forum. Almost every single thread has at least 30 pages or something. My time would better spent reading an actual book. A lot of forums I find are like this. (i.e. my favorite author's website, website for a TV show I like, a philosophy-ish forum, I just can't win)
AGN is much more like a chat lounge because the signal to noise ratio is manageable by a human brain. I don't know how people interact socially at a site with like 50,000 users. I would only post at a site like that to get an answer to a question or something. Socially, however, everyone is faceless.
For better or worse, I feel like I know people here.
