Edit: This wasn't a derogatory comment. I merely wanted to point out that the Author probably isn't a mediocre coder and those people that are probably can't touch 10000 people in just 2 days. I really like thetoolbox.cc.
I would probably call myself a mediocre coder compared to the average HN'er.
But I don't think you necessarily need great coding skills to reach people. The Toolbox really is nothing more than a customized WordPress theme, and I'm sure I could find lots of similarly successful sites that are not overly complex from a technical point of view.
