Hey Tonberry, thanks for the feedback. The logo is not currently trademarked but I'm looking into my options there. I definitely don't want to restrict use (so you can get a tattoo or make a poster or anything); it would be more of a defensive measure on my part.
As for the graph feature you described - I like the sound of it. I think it would be cool to visualize relationships like that - especially with high numbers of users. That's a feature that will come after the core components come together though: basic relationships, groups, events, search, messaging, etc. Once the basics are figured out and if there are enough users, I'd love to spend some time getting a social graph together.
You should see some more stuff to play with by the week's end
. Thanks again for the suggestion, I appreciate it.
