Not sure when it was launched, but I have just discovered Blawg Republic, a self-described legal news and commentary search engine. It is interesting for the two vantage points it provides on the latest news and commentary from the legal blogging community. The first, Top Blawg Posts, lists the 20 most popular items posted by legal bloggers, with hourly updates. The second, Top Links, lists the 20 most linked-to items among bloggers. Plus it includes a search interface for searching legal news and blog items.
