I note that this question implicitly prefers questions with a general topic but in fact very localized content (one's life story + a question of type 'What should I do?').
For example, one I asked a general question (i.e. if one can use his/her personal e-mail instead of institutional) then it was pointed out that in fact there were such question before (as a side part of a compound/story type question).
AFAIK it is not a good practice for a SE site.
First, it makes things less reusable.
- An answered question makes less sense to others.
- It is harder to find.
Second, it makes harder to make meaningful answers.
- If there are more subquestions and answer covering only some may be accepted.
- As a specific context is given, the answer may not be true in a more general one.
