skitch screenshots for mac

Skitch is a great screenshot capturing program for the mac that also has integration with flickr (and skitch.com) to upload the images after they have been taken. Extra features such as watermarking, highlighting of areas of the screen, writing and drawing on the picture with the edits being individual items or layers and therefore movable, make this a very feature rich capturing program. I'm very impressed with it so far in my limited mac experience. My skitch site is at skitch.com/absoblogginlutely. The one photo I have uploaded (and to flickr too) is a picture of some very bad redacting by the army
