Good and insightful post, with stats about the amount of traffic received. Even just before New Year, when everyone was presumably on holiday, TechCrunch brought in almost 10'000 visitors over 3 days (but this spike also includes a Hacker News post, so I would estimate the amount of actual TechCrunch traffic at about 7-8'000 confirmed).
It's a good story, and the author, Roberto Martinez draws some conclusions from the experience. The most important one is that TechCrunch is more useful as a source of early credibility and links than as a source of raw traffic.
