Are there really that many Clojure IDEs available? I suspect you're conflating IDE and text editor.

I don't know at there are a ton, but the first one that comes to mind for me is lighttable, which is pretty rad, if you ask me.

I think the only major one is the IntelliJ plugin (though SLIME is a sort of marginal case).

don't forget the Eclipse plugin Counterclockwise: https://code.google.com/p/counterclockwise/

He only said "editors", so he's still in the clear.
