Skitch Version 2.5 App Update
Evernote just updated their famous photo-editing app, Skitch. Version 2.5 (for OS X and iOS) adds the ability to edit PDF documents. It also adds an annotation feature where you can post something and other users can see what comments you made on their document. Finally, it adds stamps, which offer feedback. For example, you can place a stamp with a heart indicating that you like something or a question mark indicating that you don’t understand.
