Steve Bradford has a very complete and useful set of links to blogs, news services, and the like that he uses to keep up with his professional reading. I read most of the same sources that he does, funneling all that have RSS feeds through my Feedly account. The one thing I do that he doesn't mention is that I have used Westlaw's alert service to set up a bunch of standardized research searches to run every month to flag cases and articles that seem likely to be relevant to current or ongoing areas of interest. Oh yes, and I also subscribe the the Green Bag.
