We just launched the public release of Pownce (no more invites!) with some new features. My favorite feature is the mobile event view but all the other Pownce team members seem to like the Friend Importer stuff. Basically, you can try to find your friends on Pownce via your email contacts or other social networks including Gmail, Yahoo! Mail, Digg, Flickr, Twitter, and Facebook.
I called it "profile bling", mostly because that was all it was good for. It looks cute and helps your friends know what other online networks you're active on.
With the Friend Importer feature, the *bling* is actually helpful in matching your friends on other social networks to potential friends on Pownce.
It's nothing fancy; the process is something like:
- ping the Facebook/Digg/Flickr/Twitter API for the user's friend list
- match results to Pownce users based on username, full name, email, and/or *bling*
- return potential Pownce friend and let the user decide who to add as a friend
I'd like to say that I had secret plans all along to use that *bling*. Actually, I kind of hoped someone else would use the *bling* for their secret plans... I'm looking at you, DataPortability.org.
