edutopia.org - My story began while I had to stay home to convalesce from a recent spine surgery. That sounds bad, but its all good now, so no matter. While I was home recovering, iPad in hand, I began exploring. Edutopia was a good place to start. I had already been using the resources on this site for several years, and had meant to post a note, or read an article... One in particular, commenting on the value of Twitter for establishing a PLN, piqued my interest in exploring that medium.
