I'd like to try your product but I'd rather you send me an email after two days saying my subscription will expire in 24 hours than pre-paying by credit card. Make it easy for people to try and not buy and you'll get customers. Trick them and you'll lose the best ones. Fix it and I'll give it a try.
From screenshot, I think digg reader is more minimal (minimaler?) than this.

Already super happy with Feedbin.me.
Feedbin is a good service. If you like them, you should stick with them.
