I think the author did not really get the motivation behind the LightTable concept. For those interested, it was this talk that inspired the guy(s): http://vimeo.com/36579366
It's about the instant feedback during development as opposed to the classic change/compile/reload cycle.
Especially for concepts it's important to understand the intention rather than picking on it point-by-point (which in itself, while true for the most part, seems rather pedantic to me).
One thing I noticed: Could you link more prominently to the github page/repo of the project? One has to click the "watch" button to get there (which I didn't know before, so at least I learned something :D).
My idea would be to make a prominent "on github" link or link the big title to the repo.
Of course it isn't a bad start. But, as others pointed out, the price point is pretty high as it is merely a bet on the product.
I myself would have considered buying/donating, although I wouldn't use the first version (not doing any Javascript or Clojure projects). But I see value in what is planned here and would be willing to bet twenty or even thirty dollars on its success. It would be a bet that the final product, which I basically bought, is good enough that people implement plugins for it that I could use (ruby/php/java/actionscript/etc).
But $50 is a pretty high bet in this case, and I would bet that I am not the only one in the described situation...
I think this is a great idea with lots of potential, because one can easily put too much effort into the naming of things (as every hacker knows it's the only difficult thing besides cache invalidation).
But I have to ask: Why did you call your company "Nomvilla"? And am I right that it basically means "House of Names"?
When visiting the homepage, I didn't realize this was an additional service to an existing (and unrelated) iPhone app. I just saw the unrealistic (albeit funny) conversation on the iPhone and the (real?) testimonial next to it and left the site. It wasn't until I read your comment here that I realized what the site is all about.
So, I think the idea is great, but I also think your comment here does a better job at explaining what the site does than your actual homepage...
