In this post I wish to discuss and ask for some suggestions which address these concerns (most answers on the question regarding voting do not address what can be done about it) and which I think may help maintain quality on this site. I have been using the site just for 3 months, and am not very experienced so I request all to excuse me if I am suggesting something silly.
There is a genuine concern that sometimes good questions (especially the ones that are relatively advanced) do not get enough attention and remain unanswered presumably because the number of questions on m.se is large and each question spends lesser time on the front page. There has been a suggestion to split m.se into more sites but it has its own problems as can be seen by looking at the answers there. While I would not advocate splitting the site, but I have to say (based on my personal subjective feelings, and I am curious whether more experienced users agree with this) that : questions which are relatively advanced but not research level (so that they are out of place at MO) do tend to get suffered more due to the traffic despite the fact that there are enough users who would have answered these questions if they were not buried inside larger pool of elementary questions.
I feel that in order to help this situation, would it not be nice to have a new tab (in addition to the usual 'newest, featured, ..., unanswered' tab) for advanced questions which just slightly fall short of being appropriate at MO ? I would suggest that users be given an option to indicate (by checking a box) whether their question falls in this category or not. Users with high enough reputation / moderators could make sure that only advanced questions are seen in this tab and may have the power to transfer more questions into this tab. Would not separating the more advanced questions be helpful, assuming that it can be done ? I feel that this feature would attract several MO users to visit and answer questions on m.se who would not do so otherwise because their primary interest may be in advanced questions which are buried in a pool of more elemetary questions on m.se.
Coming back to the voting issue I feel that the following may help :
1.) There could be messages requesting a user to consider voting more if the user views large number of questions (say 5 or 10) without voting any of them.
2.) How about having some reputation points for voting (say 1 point per 2 votes cast with some cap on the reputation that can be earned this way say 10 per week) ? What would be the advantages or disadvantages of this system ?
To summarize I would like to ask :
What can be done to maintain the quality of the m.se website in the view of the large number of questions per day so that the relatively advanced questions are able to get the attention they deserve? and What can be done regarding decreasing voting on m.se ?
