I, on the other hand, treat it as a positive signal, albeit a weak one. But at the end of the day, for me at least, a hiring decision is never about any one feature on a resume... you have to look at the whole thing holistically and try to get a complete picture of the candidate.

Somebody with just a nano-degree maybe doesn't impress so much. Somebody with a couple of interesting open source projects, a nano-degree, and some other miscellaneous education may well impress me depending on the details.

But really, it (should) all come down to the ability to demonstrate competence in your claimed skills, regardless of where/how you acquired the skills you claim.
