The Library News.com describes itself as "a collection of RSS feeds of various Library related blogs and websites. Here you’ll find the latest information about what is going on in technological realm of Libraries. We also have a finely tuned Google search engine to search through all those blogs."
Very nice! A similar though more modest tool is the Knowbodies Library&Technology Metagator, which I monitor feverishly many times a day to find stuff to blog about.
