About a month ago many speculated that StumbleUpon was for sale. EBay is asking for the equivalent of a king’s ransom, rumored to be $75 million. Given that StumbleUpon has revenue in the range of $5 to $7.5 million, the asking price is not completely unreasonable.There are not many companies that can buy up something for that kind of figure that would be interested in a property like StumbleUpon. Do you really see a major media property, like News Corp, buying StumbleUpon?

StumbleUpon is all about site discovery. I used to click on the “Stumble!” button and figured it would return me some random site based on the categories I said I was interested in. But then I noticed that the more I used it, better sites were being sent my way. This is because it’s not actually random, but rather sites are served up based on a series of processes that go on within the StumbleUpon Recommendation Engine.
