As a pseudo/semi-functional academic, I am always interested in ways of tracking contemporary writing, ideas (memes) in and around the stuff in which I have interests. i/e/ how to drink from the fire hose without drowning. One little trick I have been exploring is to do a Google Blog search for the key words/phrases and to copy the 100 RSS feed into my RSS aggregator. I end up with an always updated set of posts, many of which often point me to a publication I have missed, a conference, or call for papers, and even occasionally some useful commentary. And you can filter and search the inputs from this into the aggregator with the search facility in the aggregator.
