The approach so far has just been to increase the number of closed votes needed. Originally it was 3 then 4 and now 5. But perhaps we should be raising the minimum reputation instead?
For example, Interview advice on reason for wanting to leave current job was closed. It seems that there is a distinct lack of awareness about Jeff's stance on this:
- Questions about social engineering, management, or career building, ergonomics, or other “soft” topics related to development work.
The “winners” of this poll, items 1-7, map strongly to my idea of what we built Stack Overflow for.
