Augh.. internet anonymity compromised!

So someone over in the Doctor Who community posted about MPT's Who schedule which led to some of the Marylanders, like myself replying. Turns out a someone may (i.e. likely does) know me. And she confirmed that I have probably successfully identified someone on her friend's list (even if I can't figure out who she herself is...)

I've never treated the internet as some source of anonymity, but it's still odd when you stumble across someone you know when you're not expecting to..
