New rails budgeting application

Hello everyone.

A love affair with Rails and a habit of overspending led me to develop
a money budgeting application called Walletproof.

We just launched at: http://www.walletproof.com

The speil:
Walletproof is a personal finance web application. It's meant to make
keeping a budget as simple as humanly possible.

When a user is keeping a budget he/she can recommend deals to the
Walletproof community, thus springkling the whole thing with a bit of
web2.0 fairy dust!

I would greatly appreciate any comments or suggestions anyone has!

Cheers,
Geir Freysson.
