I checked out del.icio.us using the PLCMC account. I enjoyed browsing the the various blogs posted by others. I found one by one of our own PLCMC folks and decided to check it out. (yes, Chris, its you!). I was interested in what was linked to a "READER'S ADVISORY" tag and saw a post by Chris about the site called, allconsuming.net. I set up an account for this and think it will be fun and helpful, although today it was a little slow opening up links.
I even set up my own de.icio.us account but am a little confused on how to start; will play with it again.
This is the the site I looked at: http://del.icio.us/PLCMCL2/ReadersAdvisory
