Answer Hub - Questions being ignored

Answehub is a bit of a desert.

Most of the time when I end up there (through google or whatever source), the question will be unanswered.
The questions which are answered often have not accepted a solution or are in a very messy state. It’s mostly unusable as a qa resource.

It could be greatly improved by using mechanics sites like stackoveflow: Modding, reputation points towards privileges etc…
There’s very little incentive to answer anything, do karma points unlock anything?
