I'm not sure what you mean about the TinyMCE being wrong, it is correct in my copy.
<add key="TinyMCE:BasePath" value="~/ClientScript/tiny_mce344/"/>
This is correct for the latest version of the source code in the repository.
We won Best Other Open Source CMS back in 2007, I saw the same tweet but I'm not sure why someone decided to blog or tweet about it as if it were current.
Best,
