We are very sorry to let you know that Springpad will be shutting down on June 25th. At that point Springpad.com will no longer be available, all online and sync features of the mobile apps will stop working, and your personal data will no longer be stored on our servers.
They probably couldn't take it from the huge competitor Evernote. I hope they will help the users with an export to Evernote option now.
Evernote is an incredible service that I like and use a lot. Nothing comes even near it for what it can do. I use it for so many different things, like Project Management, GTD, todos and as a knowledge base to name a few things I use it for.
