TechCrunch: eBay's StumbleUpon Acquisition: Confirmed at $75 Million. eBay's getting a real-time context generator. Each time you thumbs-up or tag a page, you're joining other people who share that interest. So when you build Skype into the StumbleUpon toolbar, those contexts will enable, if not trigger, live conversations among millions of Stumblers. eBay's been investing in context generators like Meetup.com for a while.

Paid Content: Exclusive: Former Cisco Exec Mike Volpi In Line To Be New Joost CEO. He's a former Skype director, too, one of the ones who sold out to eBay. Hmmm, who is Joost's eBay?
