I wrote about the Jing Project last year, and the development has been coming quite nicely. One of the features I wanted to see, Flickr integration, has been added along with the usual fixes and improvements. Jing is a quick and simple way to capture screenshots and screencasting. It's not filled with features that most people won't use, just the ones that are useful and will make your experience better.
