I'm a chemistry major spending the summer learning to code, so this is all a learning experience. It's only been about 3 weeks so I'm happy to have gotten something functional out of it. I'm really hoping to get some good feedback from HN.
The about page on DailyDo.it genuinely describes what I set out to make. I have spent 3 years in university trying to keep track of everything I have to do; the result is usually a big mess of tasks on notepaper, my whiteboard, post-it notes, etc. I've tried using online versions, but they all seem so complicated and messy, which is the opposite of what I want. DailyDo.it is meant to be as simple as possible - the challenge of maintaining simplicity was certainly a surprise, but I think it worked out well enough.
As for the next steps, I'm aiming to have the team version (http://dailydo.it/about/team) up and running very soon. This will be a paid service that allows teams of people to share and collaborate on their tasks.
