One more note from the other night's activities: introductions in a geek group have changed.
Once upon a time, when I used to run a LUG and there was a get-togather, people would introduce themselves by email address since more often than not you would know their contributions to a popular mailing list better than their name. Blogs seem to have changed that a lot. Self-respecting geeks (in a certain circle) will now introduce themselves by blog URL, not project or email addr. The concept of online identity is fluid enough to be a joke anyway but I wonder how I'll be introducing myself in another 5 years.
