This is great. Data Mining went through and used Blog Pulse and all the link tracking services (IceRocket, Technorati, Feedster, etc) to track down the Technorati purchase rumor:

There is a pretty big rumour going around just now about the acquisition of Technorati by an unknown big player in the search space. I find this really interesting – not because of what may or may not happen, or what certain people think may or may not happen, but because it provides an ideal case study in how rumours propagate through the blogosphere. I intend to track this pretty closely and write up on how things progress and how we can track the story. But this post is just going to give some preliminary information.

I hope there’s a solid followup as I’ve been meaning to do the same thing myself.

Update:

Data Mining wasn’t the only blog which wanted to analyze this meme.
