Learning by Doing

Every time I get one I think, did they send that to me because they wanted me specifically, or did they just spam their whole addressbook with the eager assistance of whatever new site they joined? The thing that’s keeping me from signing up to these sites is that I don’t want people to think that’s an OK place to contact me, and I don’t want to just leave some grumpy message about how I don’t ever check my wall messages. I’ll probably end up joining them, if only to defend my identity from Spock.
