I think it's fine for you to share suggestions (links already provided) but I'll pipe in and say that I like it that scores are not shown until you hover over them. It's subtle, but to me this method of displaying votes puts more of a focus on the content of the discussions rather than who's getting the most 'points' for what they said.

I wouldn't mind an option to view the site's text at a bigger size or darker, perhaps in the user settings. My eyes get strained after a while! (Or I need to upgrade my glasses prescriptions.)
