Yes totally agree with this. Posts can be sub-categorized, tags can be created and responses can be scored based on how effective or important they are (even though this is already a feature currently).

I did a similar exercise for Amazon earlier where reviews are only sorted based on the rating & date posted and not on any other feature. There are many other intelligent ways of sorting and rating posts, creating scores to them and show only those that are relevant by creating AI agents that can give what the user wants.

I can contribute too.
