Fill in the blank, "I'm going to _____ every day." Thinking of something? Great! Now go out there and do it, then return to the tool and click "I did it today!" You'll be congratulated and given the opportunity to write about your experience and post a picture.

At that point, the picture becomes a link in your productivity chain. After you've formed a few links in the chain, I bet you won't want to stop. But if you do stop and miss a day, the entire chain breaks and everything is deleted.

Now, if you just want to use the tool for just that, all by your lonesome, that's just fine. But we've included a social aspect to it as well. Whenever another person is doing the same thing as you, each one of your chain links will be submitted to a centralized place where you'll be able to explore and upvote others' chain links and post comments to everyone.

On the front page, you'll see the top 20 popular chains and the fastest growing chains for today, as well as the top comments and featured users. Next to each chain is a plus sign that, when clicked, will enable you to do that same thing each day, too. You can also explore and find interesting chains and users.

The time interval is adjustable. You can do something every day, weekday, weekend or week.

The project was inspired by this post: http://lifehacker.com/software/motivation/jerry-seinfelds-pr...

We're launching on Friday at 10PM CST. Everyone who registers in the first hour will start with 50 karma points, so bring a friend! If you have any feature requests, just let us know and they'll be waiting for you at launch.

Common wisdom is that it's dangerous to let you all in on our secret before we're out there, but we wanted to give you the opportunity to make this tool better in your eyes.

Thanks for your critique guys!

Update: First feature request will be implemented for you: A vacation switch that you can toggle on and off. If it's on, your chains are frozen and won't be deleted.
