Yes, it is, but after I read a thread here that happened to detail communication problems I had on other forums, I stopped trying to socialize on non-ASD forums, so I have very little recent experience to compare with WP.
I never had much interest in participating on topical forums/boards; I mostly hung out in discussion forums. I've grown weary of the endless nasty undertones, people who don't actually want to get to the bottom of anything but just want to 1+up each other and see who can come up with the funniest/most creative insults, snark (and hating myself for being drawn into it), and dismissals, and (ironically, now that I think of it) people continually assuming that I'm trying to be mean to them, that I'm posting in anger, that questioning them implies that I disagree, that I always have some ulterior motivation, and ignoring what I actually say in the process. That happens here, too, but far less often.
I feel more comfortable here relative to other forums, but not completely comfortable; the anxiety that my comment is going to be misconstrued and make someone angry lives on within me due to years of that experience, and, being now more aware of all the snarky subtext that tends to go on online, I sometimes get paranoid that it's happening in a thread to which I'm subscribed and I don't see it. Also, when I don't understand people I like to ask a lot of questions, but I don't think most people care to go into that much depth, especially on "light" topics. But that's true of most places online.
