I Created a Startup Aboard a Bus from SF to Austin: Pairwise Launches at SxSW

That said, the fact that you label it a "startup" instead of an "app" is a pet peeve of mine. You created an app on the bus, not a startup business (though perhaps one will develop around the app).
1) I don't understand why it uses FB Connect but still forced me to enter a name, e-mail and password.
2) I understand that this iteration is closely tied to SxSW, but it shouldn't have automatically populated the Austin and SxSW tags for me because I'm nowhere near there.
3) It would be cool to see the global public stream, or the stream for any particular tag.
Good luck!
personally, i would like the ability to use openid, or just a simple password, and also to be able to use, say, a laptop (eg via a maps or lat/lon interface). but i guess i may be a technical luddite.
