I'm curious how you found this blog and what attracts you to it. I never would have, except for my son. It's definitely geared towards young nerds, and most of the posters are guys.
My intro is a few above yours. I found this blog through my husband, who is a much more typical LWer (male, atheist, computer programmer, sci-fi fan).
I guess what attracts me to it is that most people I know write me off as unreasonable or cruel for trying to apply logic to situations where they go by convenience or custom. I would continue more or less doing this even if I never found a community of others, but it is comforting to see a community out there. The main turn-off for me is that most of what I've read here doesn't apply to my life in a useful way (as far as I can tell).
