Well, I'm pretty much just as crappy with girls online as real life. I have NVLD (nonverbal learning disorder) specifically, though, it for all intensive purposes works like AS, but yeah. Nonverbal learning disorder basically means your verbal IQ is like 130+ but your nonverbal is like 80. So for me I'm kind of thinking verbally all the time, so transferring it to text is pretty easy.
My sister, though, one time she and her friend IMed me, and her and her friend were like "Wow, you sound like, cool, online." Once I learned to use correct grammar and spelling, I'd be like 13 years old and have people tell me I sound like I'm in college when I talked online. I don't have very many online friends anymore, though, I used to have like 20 friends, but now I'm down to like 4, and it's now hard for me to reconnect to more people online for some reason. I think it's because my like, home board, Gundam.com/AnimeX.com, died. And that board was a constant in my life for a lot of years, I was on it from 2003 (or more likely 2002 if we're counting Gundam.com) to 2008. It was a really close knit board (maybe to it's demise) and yeah. I still talk to people from that board, though, that I've known since 2003.
But uh, on this board in particular, things aren't perfect. I feel like a bit of an outsider on this board due partially to having NVLD, but also my interests and viewpoints are pretty different a lot of times on this board. One particular problem I have is I make really long posts, so it becomes tl;dr for a lot of people to read them.
