Swappa has just been launched as a better way to buy and sell gently used, fully functional Android devices. Thank you for feedback...
Please don't make me login with facebook. I do have a facebook account but I don't feel comfortable using Facebook connect (like many others).
I won't mind twitter or plain old OpenId though.
I know, this was a big decision I went back and forth on. And I've read all the HN threads discussing whether or not to use it. I ended up going with Facebook connect because it's so easy to get a name and profile picture, and from what I can tell, the average user doesn't mind. I've also tried to state clearly what information is and isn't used.
