Last week I tweeted:

Is this statement true for everyone or just me? “Dominant source of traffic to medical blogs is not search but direct links from Twitter”

I received varied response, Pascale Lane and Michael Katz agreed, while Dr. Canapari disagreed:

@kidney_boy search for me. By a significant margin

And Matt Sparks called me directly to tell me that I was crazy; the analytics he has access to show search by a mile.

Here is the data for the last month at NephJC, Direct links (bookmarks, e-mail links, hand typed URLs, others?, etc) and Twitter (t.co) represent 75% of traffic with Google mopping up a distant third.
