Ryan Seacrest, Ellen Degeneres

We like Twitter when it's done right: Funny, useful, or insightful — yes. Overly self-promoting, too frequent, or just plain boring — not so much. Chuck fans, you've made us proud with your Twitter campaign to save your beloved show from cancellation (click here to join the #savechuck movement). Oprah, please step it up, because right now you are #JPB (just plain boring).

Since it's #followfriday in Twitter-land, we've made a list of our top 20 current favorite Twitter-ers. (In entertainment Twitter-land, you can never tell whether the people are real or whether their publicists are doing the tweeting. We just think these are funny.) Tweet us your favorites! And if you still just don't get it, we won't judge you. Click here to learn more about Twitter.
