If you haven’t signed up for an account on Tumblr yet, what are you waiting for? Since my last post on tumblelogging, David has added support for mobile posting (Thanks!) and support for integrating RSS feeds (either recently added by David or recently noticed by me…) so you can tumblelog your Flickr or del.icio.us postings (or anything else with a feed for that matter).

With our new arrival I haven’t had much time to blog, but have really been enjoying the simplicity of throwing some random thoughts, pictures and links on my tumblelog.

I updated my original tumblelog post, but I wanted to add this one because I just can’t help but imagine the possibilities for teachers and students.
