Really? I have noticed a few nice subreddits about Asperger's. The /r/neurodiversity looks good, it doesn't have the "cure" mentality with most of the aspies there. I also haven't seen much of it in the /r/aspergirls subreddit (this one's specifically for women on the spectrum). Then again, I don't look at anything on reddit that often.
The /r/aspiepartners subreddit is mostly a mixed forum for NT's and aspies in relationships where both partners can post there, so despite listing FAAAS and "theneurotypical" site as resources, it actually doesn't have any talk of the "Cassandra Phenomenon" or have the same kind of toxic environment as ASPartners on Delphi where they blame all relationship problems on the partner with AS (in fact I believe that this is actually against the rules of that subreddit). Given the nature of Reddit though, where the creators of a subreddit tend to create their own rules and that there's not really any site-wide moderation, I surprised that those "cassandra" people haven't yet tried to create their "NT-only" subreddit where they could bash aspies to hearts content like the forum they created on Delphi.
EDIT: What is up with this new Captcha? GAHH. I can't tell you how many time I had to post that before my post went through and didn't disappear.
