TorrentFreak has more presence than the combined presence of Bloomberg and Washington Post! I am sure that will change typical marketer’s ad placement strategy.

Where presence is the percentage of headline space a source occupies over the 30-day period. This does not include the related discussion links.  This latest techmeme service is clever. List creation based on presence puts importance of time at the center of media monitoring framework. You are in for a short time window and you have to keep hitting to sustain your presence (unlike Pagerank based popularity)

Detailed explanation of the presence methodology –

A source’s presence is the probability that a random Techmeme headline at a random time over the past month was published by that source. The Leaderboard ranks sources by presence. What is a source? Sidestepping knotty issues of ownership and affiliation, sources are simply identified by the branding a publisher chooses. So blogs are generally distinct sources from their parent site. Thus, Saul Hansell writes for two different sources: Bits (the NYT blog), and the New York Times proper, even though the New York Times Company publishes both. The same goes for CrunchGear and TechCrunch and other blogs contained in blog “networks”.

I think sharing OPML for enabling mashup is a brilliant move. This will be key as Techmeme and Google news begin to overlap on the type of sources they cover.
