Another problem is that the HN crowd has been getting inundated with a ton of 'Show HN: AppName v0.001' posts for a while now. There are some obvious benefits to doing this, like getting early feedback from tech-oriented people before chasing the general public's attention, but I wouldn't be surprised if the HN crowd is getting a little weary of wading through the onslaught of such posts.

Note: I actually think Grid's v1 was pretty well put together (based on the demo video). I am mostly referring to the half-backed Bootstrap sites with nothing more than a sign up form.
