Letehn, I don't know where you picked up the notion of Mathias Richter being YC's creator, but I'm fairly sure it's wrong.
The site was set up by Mark Richer and his wife, I believe. Also, our Google ranking is not excellent...
Feel free to edit the page to reflect those points. (Also, I'd remove the "100-200 new posts a day" type stuff, as that's likely to change over time).
