I subscribe to Squidoo Lens of the Day, and this is the one I got today. It is relevant to my profession and has got me thinking of how to incorporate Twitter into my Grade 3 classroom.

About this link in a nutshell:

"On March 10th Union Square Ventures put on a conference called Hacking Education. The idea was to get a bunch of smart people in a room to re-imagine how education could (and should) work in a web 2.0 world." (opening sentence from email sent by Squidoo Lens of the Day).

Thousands of tweets (from during the conference) have been distilled into a few hundred relevant and coherently grouped tweets.

Kudos to Alex Krupp, whose Squidoo Lens it is.
