I knew that when Evernote purchased Skitch they were destined to screw it up.
Sure enough, it didn't take long.
First they started pushing people to use Evernote accounts. Skitch had done this too, insisting that you keep a Skitch.com account in your 'sharing' options, even if you had no interest in actually using Skitch.com.
For a while, Skitch.app would actually create an Evernote and a Skitch entry in the Share preferences, and every time you deleted them, Skitch would come right back and re-create them. Because why should users get to decide what to do with software they install on their own computers?
