Folks, I am the guy behind this project. A friend of mine mentioned he saw the site mentioned on hacker news, so I came to check it out. If you have any questions for me, don't hesitate to ask, as time permits (and two little boys), I'll do my best to answer them.
As it exists right now, there are some glaring omissions. I would imagine that showing authors in the search results next to the titles would not be prohibitively difficult.
Proper threading of posts would probably be considerably harder, but would provide immense value IMHO.
