I have been using Skitch for a while now and more so more recently for making screengrabs, annotating screengrabs and for sharing them.
I have had the free version since it came out and due to my increased usage was considering buying the $20 plus version that has a few more features.
Well as of today, Skitch has been bought by Evernote and as a result the plus version is now free.
So if you have been sharing screengrabs and want more than just the built in version in OS X then get Skitch.
Get Skitch now in the Mac App Store.
So glad I didn’t get the $20 version when you first mentioned it … all of two days ago!
Me too.
