3) Sticky Notes

The first response you might get if you add this helpful widget will be "but what about the wall? Can't you just use that?" They're referring to the built-in Facebook app that allows friends (or people who have access to your Facebook page) to leave a messages for you publicly. The problem? Most walls tend to be a laundry list of social comments and inside jokes that eventually blur together, especially if you get a ton of them. If someone added "meet with team at 3 p.m." to your own wall, for instance, there's a good chance you'd miss it. Sticky Notes are big and come in a variety of colors (we prefer the standard yellow). Created by J-Squared Media, a small widget company that sprung up in large part because of Sticky Notes' success, the app already has around 200,000 active users. You can leave notes for yourself on your own page, or you can leave them for colleagues (provided they have the app as well).

4) Blog RSS Feed Reader

Another way to keep project management away from your e-mail inbox (where it doesn't belong) is to have internal blogs. If you've made that leap, why not feed them to your Facebook page? We picked this reader over several other RSS widgets on the Facebook App list because it can pull from enterprise-worthy blogging apps such as Movable Type. As updates to a project occur, the blog entries feed through the Reader and onto your Facebook page.
