I just wanted to point out that Google just released a blog search tool (in beta); presumably this will compete somewhat with Technorati. I haven't tried it yet and will be interested in people's impressions.
And on an unrelated note, in case you haven't noticed, I've been on somewhat of a blog hiatus recently. This is likely to continue for a while longer as my research projects are requiring a lot of time lately. It's nice in this respect being just a sub-blogger here: I don't have to worry that everyone will quit reading the blog just because I'm not writing anything.
