You should add some screenshots so people can at least see what you're trying to sell. That's one of the first things I look for with anything like this so I can get a feel for what's being offered.

Otherwise maybe it's prematurely on HN if you wanted to get best value for hitting the front page?

Just put a link to this on your landing page. Honestly, I am rarely interested in what the creator of a product wants to tell me about it. I just want a brief description of what it is and why I might want to use it, and pictures. A demo is better again, bit I want to see your product, not read about it.

Well the problem now is that you've got your publicity before you were ready for it. Now when you do have a demo, your publicity has already been and gone.

I like the landing page. It looks good. But without a demo, you're already just-another-startup.
