I just posted about LibWorm not too long ago, and then today I read about LISZEN on the ALA TechSource blog. If aiming for a Google-like look, LISZEN's your search engine. Perhaps that's because the creator used the Google Co-op to build it.
I'm really not sure which one is better though - they both pull from library blogs. LibWorm has 1500 feeds, and LISZEN has 600. Perhaps LISZEN has superior search capabilities because it uses the Google platform. I'm really not sure.
Once again though, I have to sign up for something to get my blog added. I am supposed to add my blog to the wiki first, and in order to edit the wiki, I have to create an account. Sigh. I have way too many accounts to keep track of.
