Yeah. If I see Coffeescript I generally tend to feel a bit of reluctance to get involved.
Sometimes I'll translate it into real Javascript but most times I will just pass it on and saying "nevermind". It's just not the "real" thing and something has to be truly great or promising for me to bother with the indirection.
That, and like VBScript, I just don't like Ruby or Python, so I'll stay away from projects using it.
