Hi, I like the ability to rapidly get started and quickly share (far better than Remember The Milk on that point).

There are other apps/services in competition but that is ok - proves there is some semblance of a market out there.

I'd say you should get it infront of as many potential customers as possible ASAP so you can move from hypothesizing about customers to having validated learning about them.

You're right to release early - you need to start qualifying WHO will pay and how MUCH pretty soon (if you wish to turn this into a profitable business).

Your unique selling point may well be the speed/ease of use and ease of sharing. I'd pay at least £1 per month for that.

Hope that's useful feedback?
