eBay buys StumbleUpon

I’ve been meaning to write up a quick report from the NILS Conference 2 weeks ago but I’ve just been swamped. I will get some thoughts out on that sometime soon but I wanted to quickly note that eBay has purchased StumbleUpon for $75 million in cash (the ‘in cash’ part is amazing too.) I often use StumbleUpon as an example of a business that got popular by starting as an extension to Firefox. SU was mentioned in our NILS presentation 2 weeks ago as a widely-reported rumor. Now it is fact.
