Upvoting questions would increase the likelihood that someone would answer it. Its a variation of the "put bounty on someone else's question" suggestion.
At first I misread this as 15 points + 10 x question upvotes, which I totally disagree with because it overvalues the upvotes.
But with a small extra incentive, maybe this is the nice middle ground between offering bounty on others' questions and the current system.
A couple questions for clarification:
- How would you have them work with the rep cap? The same way as accepted answers always do?
- Suppose a question is at +3, and you get the accepted answer: +18 for you. Then, two more people come along and upvote the question. Do you get 2 more rep for those upvotes?
- What about downvotes? Is it fair if they have no effect on this system?
As noted this would be highly open for gaming. But that's not my concern.
This encourages noise. Lots and lots of noise. Questions with a lot of upvotes already have interest and answers. Tendency has already become that for any question with 5+ answers, at least two of them will be content-identical.
This solution provides more of an incentive to answer questions that don't need the help. On the other hand, there are questions with one or no upvotes because they aren't glamorous or sexy, and there's one answer so they do not show up on the 'unanswered' list anymore.
Those are the questions that need extra help, because there isn't interest in them. It's hard to come up with a solution that doesn't involve gaming, but those questions need help.
There was a recent question "What should I do if my partner aligns his brackets wrong", when I saw it, it had 6 upvotes. So, a lot of people would then want to add their two cents, in order to get a shot at getting the extra bonus.
Perhaps this can only apply to questions which are over a certain age. Maybe they gain additional "Accept" points the longer they stay unanswered, which would encourage users to dig around in the older "unanswered" bin to find some additional rep and close out the languishing questions that have fallen off the front page.
