I've written about Technorati's support for microformat search and the uptake of the microformat movement in the blogosphere. Here's an update of the volume of hReview entries in Technorati's engine:
What are the implications? Now that microformats are hugely a part of the non-blogosphere, a search engine that provides access to microformats needs to be indexing these Yahoo! local pages. Technorati is clearly moving away from being a blog search engine (they were smart in picking a name which doesn't contain the word blog in this regard), which is why they claim to index sites, not blogs. It will be interesting to see if the aggresively go after this Yahoo! microformats data.
