Since we are on this particular topic, let's brainstorm some of the things we can do to get a list of close friends. I have a few from Facebook.
- access the friends list api, particularly the close friends list from Facebook. Since Facebook didn't disclose how they come up with that list, it seems pretty accurate to me.
- look through photos with people who are tagged together with you. These people must be the people you hang out quite often since you take photos together with them. It should works on Instagram too.
- tags in status update. People who usually tag you/you tag should be people who are close to you. This should work on Facebook or Twitter.
Any better ideas than these?
