Heavy stuff from Obama adviser Valerie Jarrett this morning.

Or not:

“P” … what does it mean?

Aw, bless Valerie’s precious heart. She’ll get the hang of this someday. As we’ve seen, Twitter is hard:

Sen. Barbara Mikulski tweets her favorite letters of the alphabet: ‘c’ and ‘d’

Oops: Rupert Murdoch suffering from premature tweet syndrome?

Epic #fail: Lanny Davis bungles Direct Messages to Morgan Fairchild; Update: Tweets deleted

Washington Times tweets ‘aol.com’

What’s that, Senator Grassley?
