Hey, thanks! I didn't know you were on here either. I need to pay closer attention... Yeah, when possible, I have been choosing pseudo-random usernames (via pwgen) so that my accounts aren't obviously tied to me if I later decide to leave services and they don't have good removal functionality. As you may have guessed, this has happened before :)
I understand. A lot of services tend to make too much information public by default. And I think you're correct that meetup is too public. This factor hinders adoption of social services beyond the young and the extroverted.
When I see you I will show you what I've been working on.
