She links in mysterious ways

I’m puzzled by Technorati. My blog has recieved about 20 new incoming links in the last 6 days, of at least 8 or 9 are from blogs that have never linked to me before. But I have been stuck at incoming links from 128 sites for more than a week. It doesn’t seem like Technorati is updating this number as often as they update the actual links. Am I wrong?
