It's a rumor, but an interesting one. I've personally used Plaxo for years to sync all my calendar & address book info, & aside from a few glitches, it's been a very useful tool. I'm not quite sure how a deal like this would work out. I guess I'm cautiously curious for now.

"Some have said Plaxo is looking for a price of $100 million and others that it has received an unsolicited offer of $200 million. Facebook, meanwhile could stand to gain a lot through Plaxo, as separate, inside sources have pointed out to me."
