From our programmers:

- We tweaked the brightness/contrast on the green for rec'd comments and the yellow on new comments so that they would be easier to distinguish.

- We adjusted the size of the fonts and the line spacing

- We adjusted the padding on the comments

This should address feedback about size, whitespace and readability. We'll keep iterating on this and everything, but wanted to share this since we're hearing it A LOT.

Other things we are working on, but have not released fully yet:

- Improving load times

- Streamlining the mobile experience

- Improving the experience in IE 8

- Tightening up layout of articles so that comments are closer to content

- Overall individual site navigation issues

- Lots and lots of other bugs and tweaks
