The site needs some type of notification alert so we can hear a beep or something when we receive messages and comments. I use my phone for this site, so I always have to refresh the page just to see incoming message notifications
Voted A edit post. And its not a bad idea accept followers request ( when profile is private) ..
I'd like to be able to edit, but have it for a certain amount of time. I know that editing could help trolling, but if they limit your time where you can edit, it might help. Also, sometimes questions only get one or two answers and then they are forgotten. The only way you can get more answers is if you feature it. I'd like to see a section for questions with less answers for people to check out. I know there is the No Opinions section so I am meaning something similar to that.
List how many comments each question has for your feed page. Lists questions with fewer comments higher up on the page (so more people read it). Much more frequent refreshing of the Recommended Questions page, and refreshed with questions that have fewer comments. Being able to up/down vote questions based on how interesting they are. Earning Xper for voting on people's comments, but in a way that prevents vote spamming (so like 3 points for first vote of the day, 2 for second, 1 for third, .5 for any more, etc). Having tags for questions. Automatically suggesting previously answered questions who's tags match your own.
