Thing #7a and #7b - Google Reader revisited

Will Richardson's blog Transparency = Leadership thoroughly expresses my concerns about collaboration, the online community, and the hesitancy of educators to jump in.  

For math teachers, I also found a the National Library of Virtual Manipulatives which allows hands on"line" activities.

Tech Learning had an interesting post Embed Files with Ease that directs you to Embedit.in. Tech Learning had bookoos of information that was helpful.  I highly recommend subscribing to that blog.
