Thanks to everyone who offered up some feedback. Based on all of the comments I've added a few additional items to the site, while still trying my best to keep to a minimalist approach.
Included now are:
- Twitter connection to auto-update your account (uses OAuth so no username/pw necessary)
- Twitter connection to a [coffee][talk] account (this is similar to watching the table update, but through a central twitter account http://www.twitter.com/coffeetalksf)
- Simple message integration (ability to send e-mail to friend(s) to let them know where you are - secondary to this, toying with the idea of throwing in a GMail hook to grab contacts, any thoughts?)
- Ability to change how long you plan to be at the shop for
- Ability to add what you're interested in/where you're located
- Search feature
- Ability to hide/display add'l details on people in the table
I believe that's it. As always, I appreciate any additional comments!
