I'd like see how many views my links are receiving. Is that possible? Yes, it is! Here is how:

 I asked students to write in Google Docs and then share their papers with me so I would also be able to view them online. Instead of scribbling marks in the margins of printed papers, I opened each student's paper in Google Docs, highlighted text and inserted comments to clarify my thoughts, and then turned on the screen recorder (Jing) to record my voice as I scrolled through the paper and pointed to items with my mouse. Right after recording, I uploaded the finished recording to Jing's companion hosting site, and then I simply copied and pasted the link to the recording directly into the Google Doc. It was slick like butter.

First min would be good to introduce screen casting
