Twitter has jumped the shark Apparently just discovered by ad agency CEOs.
Jing TechSmith, (Snagit and Captsia) provides a great free tool for both image and screen action captures. Available for Windows (XP and Vista) and MAC OSX (10.4.11 or higher). Snagit was a lifesaver for a project a few years back. I've been using Jing across both platforms for a month and I'm impressed. Considering updating to the pro version at the very reasonable $14.95 per year.
