One of the most frustrating things about Internet resources -- at least for librarians -- is that they are not neatly cataloged like the items in a library.  Sure, Google has the "similar pages" function on its search results page, but it’s never yielded anything that’s relevant to my research topic when I’ve used it.  Most of the time, I focus on trying to find frequently-updated meta-pages about different legal research topics (for those of you wondering, a meta-page is a Web page that compiles links to lots of different Internet resources on a particular topic.  See the library’s Internet Resources pages for examples of meta-pages).  I’ve just found an excellent legal blog meta-page, compiled by Ian Best, the author of 3L Epiphany.  Ian has created an extremely useful taxonomy of legal blogs, which categorizes blogs according to jurisdictional focus, author/publisher, legal specialty, and a bunch of other categories.  There’s even a collection of other blawg meta-pages!
