A couple months ago, I mentioned the new (Mac-only) Skitch screen-capture and annotation app from Plasq. At the time, I wasn’t able to register for their mailing list (the captcha issue is fixed now, so do head over to sign up), but I just got a sneak peak at the private beta, and it’s everything I’d hoped it would be. Check out the screencast for a quick walkthrough and my initial impressions. In brief, I can think of many productive uses for it, but the time I waste playing with it will likely negate all of them.- Link to video download.
