In these irrational times, let me attempt to offer a rational explanation for why CBS bought DotSpotter. Unlike Matthew Ingram, I have actually heard of DotSpotter, and wrote about them a while ago, so I know a couple of things about this company. First, they have an awesome team of developers, the kind CBS (CBS) badly needs. Second, if Last.fm was CBS’ Radio 2.0, then DotSpotter is their Water Cooler 2.0.

OK, as I said, this is just an attempt to explain why they bought this little-known company. My sources say the price is not, I repeat, not $10 million, but much lower. Of course, CBS doesn’t wanna talk about it!
