Ask HN: Please review my startup

Hi

My startup is [name redacted] and is a platform for running contests on. (web or facebook).

I have been working on it for the last 3 months part time.

I have been getting quite a few users just at the 400 user mark now with quite a lot of positive feedback.

The main feedback I want is regarding growth and marketing.

The only differentiating point my software has at the moment is it has a free option. Oddly enough other contest platforms do not offer a free option, or if they do I haven't found them yet.

I have the roadmap written down for building on this platform a type of contest much more engaging and unique than other offerings out there.

This will be my first unique spin in the niche.

But that is going to take more time and development. My question is: Do I start marketing now, or will it be unheard until I can actually market something unique?

Also if you could please have a look over the site and tell me if the message / UI is clear.
