There are a few links like this that get submitted about every 4 or 5 days. At first I was annoyed, but now I kind of think it's a good thing- with the usership growing on this site it's probably important to hit some of these great pieces. If only the comments could be consolidated or something though...

I think this was posted before in the first few days of YC news. A recommended read.
