Soon sharing in Skitch will go through Evernote so that you will be able to take advantage of Evernote's syncing, searching and sharing features. To do this, we are making a few very important changes.
Sharing in Skitch will go through the Evernote Service, which means that you will be able to access your Skitch notes on any computer, phone, or tablet you use. As of October 10, 2012, the Skitch.com website will be archived. You will no longer be able to sign into Skitch.com as of that date.
How This Affects You
Your public and secret images will remain accessible and the links to these will not change.
