Most people who spend any time on the internet know what an RSS feed is.
“RSS is a family of Web feed formats used to publish frequently updated content such as blog entries, news headlines, and podcasts in a standardized format. An RSS document (which is called a "feed," "web feed," or "channel") contains either a summary of content from an associated web site or the full text. RSS makes it possible for people to keep up with web sites in an automated manner that can be piped into special programs or filtered displays.”
As the volume of great lawyer blogs within niche practice areas continues to grow, it has become increasingly easy to follow the hottest issues within almost any area of law. Once I have identified 5-10 feeds from top legal bloggers within a practice area, I can stay on top of the latest legal developments within that area. One unexpected benefit is that you can expand your knowledge of a particular area of law in ways which were simply previously not possible (at least outside of law school).
One missing piece of the puzzle, however, is a single website which accumulates the feeds from the best blogs within a specific practice area so that you can set up a single feed to capture multiple blogs. Wouldn’t that be great?
