You might think from the URL or logo that this is some kind of official ClojureScript page, but it's not. The official page is clojurescript.org (no hyphen).

I don't speak in any official way for ClojureScript, but as an enthusiast, I wish this author had chosen a different URL to make that more clear.

Other ideas to mitigate the confusion: using a different logo in the corner; prefixing the html <title> with "unofficial"; and adding a more prominent link to clojurescript.org titled "Official ClojureScript Page".
