I know of Awwwards.com, but they cater to specifically advancements in the design aspects of the actual site and you have to pay for a submission. The usual go-around is to submit to HN, TechCrunch, maybe the Next Web or Engadget depending on your product. There are boards on Reddit and Digg that attract a similar audience to HN, so it really depends how you want to launch whatever it is you're working on. If you are looking for users I would not recommend coming to HN and similar for your audience, however if you are coming for criticism and maybe some (VC) capital, HN and those listed above can sure meet that goal.

[Edit] I found your site, cafecoders.us and would also recommend getting your SEO in place so it is easier to find you. I was using Google and your Whois lookup came before your actual site did. In fact, this submission is ranked higher. I like the idea and would be willing to help if you ever need it, http://bit.ly/MCnWmq (free).
