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?

Same "problem" here. PubSubAgent want's to connect to a site I visited about an hour before, but never had a RSS or anything similar of this site. Some say, PubSubAgent also keeps the "Top Sites" images up-to-date and thus connect to that sites. – user160924 Sep 23 '12 at 12:54

Mail comes setup with several default RSS feeds. Delete them if you don't want them.

I believe you can also just whack the entire ~/Library/PubSub folder and get rid of everything that could possibly be using the PubSub framework.
