At first: I really like the site design. It's modern and fits the purpose of the site. I just have one minor question: what do you think of the About Me section on a user's profile page?
In my opinion, there's too much contrast. Why not a light background so that the text can be dark, just like everywhere on the site? Other sites have a light layout.
I kinda relied on having a light background when I chose to use the light flair instead of the dark flair. On every other SE I checked, there is a light background. Every, but this one. That makes it hard to "Save and copy profile to all StackExchange accounts".
So, can we please have a light background with dark text?
