Ebay, the online auctions monopoly, is set to make another random web acquisition. The Wall Street Journal reports the online auctions giant is in "advanced talks" to acquire Stumble Upon, a popular service which recommends interesting new web pages for users to visit. There's no official confirmation on the deal, but the business newspaper reports the price is $75m. Om Malik came up with a heroic explanation of the logic of the combination, involving integration of Stumble Upon with Ebay's Skype internet telephone service. But we prefer a simpler interpretation: Ebay has more money, from its outrageous monopoly on online collectibles and other auctions, than sense.
