Should Facebook Acquire FriendFeed, Twitter and/or Digg?

Any other acquisitions that make sense for Facebook?

I think Twitter and FriendFeed make lots of sense. Digg is also intriguing because of the traffic and news articles.

Seesmic or tokbox would be perfect with facebook

I don't think FriendFeed is for sale

Likely true... but is Facebook is motivated... there is always a price.
