I don't find bounties to be very useful on this site. There tends to be two kinds of users, those with thousands of reputation points and those with a few hundred or less. We'll call them the 'haves' and the 'have-nots'. Bounties don't really entice the 'haves' because they don't need the rep. And, since most bounties are for a few hundred reputation points, they don't have much of an impact on the have-nots. Furthermore the have-nots are disinclined to offer bounties which would otherwise be a good tool for getting their question more attention.
A possible solution would be to offer some, possibly temporary, moderator capabilities instead of just rep points. But whatever the case, I believe that the bounty system does not work properly. Do others agree and if so what can/should be done about it?
