Skitch is a program that was recently bought by the folks at Evernote. If you’re not familiar with Evernote, then you’re missing something special in and of itself. Skitch though is a screen capture program that I think is pretty special. Now the Mac is known for having a pretty good screen capture program built in, and when combined with the built-in Preview program there’s a decent system for managing screenshots to use in documentation or to send in an email to your family member who needs to see a picture to understand how something works.
Here’s a little more info about why Skitch is so great. Skitch makes it all so much easier, and while there is no Windows version yet, it is a must-have program if you’re a Mac user. It’s a program that you must have in your toolkit.
