interview - Stack Overflow reputation in CV

Should I mention my Stack Overflow (and other Stack Exchange sites) reputation in my CV while applying for a post-graduate position?

Answer

No, you shouldn't. Not yet, anyway

In general, I think it's perfectly fine to list that information on a CV for an academic position. Depending on the profile of the position itself, I would feature it more or less prominently. Say, if you apply for a scientific programming position (or a position with heavy coding), you could list it under a “Skills” section where you would say:

C/C++/Fortran with a focus on shared-memory and distributed memory parallelism (OpenMP/MPI)
Received formal training at XXX National Lab, taught parallelism course at University of YYY, involved in StackOverflow (username: zzz) on this topic.

(if the format allows it, like a PDF, consider including a hyperlink)

If the position is not one heavily involving code-writing, you could tone it down, or even list it in a “Hobbies” or “Personal” section. Many people like to list hiking or book reading or civil war reënactments, so why not list Stack Overflow!

But… in all cases, only do it if your account is of the wow! type. You don't have to be Jon Skeet (it may take years of therapy to accept that, but that's the sad truth), but you don't want someone to look up your profile and think “meh”.
