I conducted "library" topic searches on Technorati, Syndic8, and Topix.net.
I was able to successfully feed YALSA to my Google Reader. I also added Library Journal to the list.
Searching the directories gave me lots of information I didn't need.
The advantage to searching the directories is the gathering of information that might not otherwise be found.
Undoubtedly, the more I use these directories the more skilled I'll become at finding just the type of information I need.
