SaneBox will become more accurate by importing your Facebook friends, Twitter friends, and LinkedIn colleagues. By knowing who you are connected to, we can do a better job of determining the importance of emails from them as well as from these sites.  We assume that the people you are following are important to you.  Assuming that you are friends with a reasonable number of people, SaneBox may adjust the importance of emails they send you.  If you follow a very large number (i.e., 22,000 people on Twitter), we no longer make that assumption.

If you're not happy with the results, you can disconnect from Facebook/Twitter/LinkedIn.
