I think he's getting at the fact that this is more of a resource repository and not a place to sell your designs. Still kind of a stretch to say he mis-read however.
Honest question: What are these sites actually for?
I mean, they look all swishy as a static image, but real user interfaces are written with code and mark-up and standard controls. None of the themes I looked at seemed to come as anything more flexible than PSD files. So apart from visual designers showing off their Photoshop skills, who actually uses these for anything?
Reminds me of Unheap http://www.unheap.com/
But I like it how a majority of the plugins here do not use javascript where as Unheap are all jQuery plugins
