Redesigning this site as a prototype what features or things would you like to see implmented?

These can be things such as:

Navigation - eg. should there be another button for something a lot of people would appreciate

Think about a site such as Reddit or Quora - are there things they do right that you wish they also did here?

What is the purpose of having your profile show all the replies you've ever made, is that helpful to you, or could it be?

Is there anything you see that you would change and why?

Any and all responses are appreciated?
