I find the "Know someone who can answer? Share a link to this question via email, Google+, Twitter, or Facebook." a bit messy. Could this be changed to the traditional sharing buttons that appear on a lot of websites today. I think it would give a more refined look to the sight.
Lets keep it the way it is. As @random states, text is much lighter than images.
We should be looking to reduce the load on the server.. As I ironically post an image..
Would more icons be added, or would we just change the existing ones? Either way..
