Gender in Cyberspace

My students in WS100 all denied ever using the internet to:

1. Blog (what is blogging??)
2. Date or play dating services things / or chat online
3. Play games (what's EverQuest? a MUD?)
or
4. Use BlackBoard to get their assignments

Very hard to get a conversation started on those terms. How do we conceptualize gender in cyberspace if we pretend to never use it? I thought most people were over "geeky-ness."
