As said in voloch's thread (@theojf: this meta thread is what voloch means, I am virtually certain) I vote on advice questions depending on the question. If it is somewhat specific to mathematics and asks for facts more than pure opinion, I have nothing against the (general type of) question.

According to these criteria this particular question, in particular in its edited form, I think is a reasonable (for MO) advice question. Why not collect some general advice on CV-writing as applicable to early career mathematicians. It is at least somewhat specific to mathematics and it asks for facts more than opinions (it asks for 'musts' so standard things, not something super-specific, like, should I or shouldn't I include this or that activity tangentially related to maths in my CV). To me this is also a key difference to the other question mentioned by voloch; which I voted to close (btw, as too localized, differing from the official reason).

Of course, the quality of the answers will determine a lot whether the question is actually useful. But so far things look good to me. (Except for the suggestion to include ones MO reputation, not activity, but reputation; or is this meant as a joke and I did not get it.)

Where it will end? IMO that occassionally there is some reasonable advice question answered on MO and others are closed; as AFAIK done all along its history (with some discuassion regarding what is or is not 'reasonable' for MO). Okay, it is not the main purpose, but then, while for this particular question not of much direct personal use to me I can at least see how it could be helpful to somebody, and MO seems a somewhat well-suited medium to collect this type of information.

My thoughts: I don't recall this question before, and like it. I think that CV questions are appropriate in many disciplines, and there is much that's discipline-specific. Since there is clearly no uniquely correct answer, I hope that answers specify their scope. In any case, I have edited the question, and voted to reopan.
