The march of Aspberger's online
I don't think we're much more Aspbergery in the post-internet age than before, since the big change is pre vs. post-modern. Still, the internet opens a clearer window on what makes people tick, and gives Aspberger's people more things to fold into their bloating collection of geekisms.
The strongest current sign of this is the use of the @ character when addressing people in blog posts or comments. I have yet to see this in emails or on Facebook, though, thank god. (I believe this started as the built-in response on Twitter, and people have adopted it elsewhere voluntarily.) For example, the Aspberger's guy will write "@Bill" followed by a comma, colon, double dash, etc. A simple "Bill" followed by a comma or whatever would do. But how can you level up your geek magic points if you refrain from casting the @ spell? That concern trumps readability.
Hopefully this stupid trend won't last, given that it's not popular with the young, who avoid Twitter and have no nostalgic emotional connection to conventions that were born in email.
