I am just about to submit my Tool Exploration project which explored the possible uses of Tumblr for work and professional development. I mostly was working through the lens of a public services librarian, but I think others will be able to make connections to their own workplaces as well.
I look forward to your feedback on my project! It is located at the following link: http://toolexplorationproj.tumblr.com/
I was enjoying Tumblr so much that I also created a Tumblr blog page for the library instruction program (though I doubt library administration would see the value in such a thing, and thus it is likely to remain underground…) It can be found at the following link: http://udlibraryinstruction.tumblr.com/
Next up…. digital storytelling! (coming soon!)
