Two new (US-based) law blog search tools:

Blawg.com is a relaunch of Blawg.org with 1233 entries in 26 categories. It remains a coventional searchable catalogue with brief descriptions and links to both the blogs and their feeds.

BlawgSearch is a more advanced offering from Justia with 900 entries in 40 subject categories, 169 state law blogs and just 56 law blogs from outside the US. You can browse the categories, sort the catalogue entries by popularity, by name or by last post date and save feeds for these results. A search on the other hand searches all recent posts, returning results by relevance.
