There have been other reports that Facebook may swoop in with its own offer.
After having conversations with two sources, we believe Facebook is not going to make an offer.
There is speculation that Tumblr's banker, Frank Quattrone, leaked word of Facebook's interest in hopes of starting an auction and driving up Tumblr's price with Yahoo.
We're told no such "auction" is happening.
Tumblr could threaten to walk away from Yahoo's $1.1 billion, and force a higher bid that way, of course.
