Personally, this is the first I've heard of this, in that this article has highlighted something I've been noticing not just with Facebook but, with other social networking sites and all.
Actually, I'm a member of Orkut and can't tell you how often I feel like an outsider there as well, how some not all, members tend to treat like like I'm stupid or something of that ilk.Anyways, I'm glad to see some justice being carried out by fellow aspies like yourself to make a better world in the online landscape..
