I use Little Snitch to monitor network connections on OS X, and I frequently see attempts by something called pubsubagent to connect to many varying sites. What is this program for and why does it use so many connections? According to this article it's used by .me sync to synchronize RSS feeds and bookmarks. But I don't have any RSS feeds. And if it's synching bookmarks, then why is it going to places like 'l.google.com' (and many more random ones) instead of just to .me?
