Hey - great idea: simple, original, useful - I like it a lot. FYI though, I tried signing up through twitter and keep getting a failed timed out message back. Might be a twitter issue but worth looking into. Hope it takes off for you.
Oh, sorry about that. I had a problem with outbound traffic and it should work now. Thanks a lot for your feedback!
This is a nice idea! I cannot sign up with my twitter and it time outs.
