Can you bump the Comment font size by 1?

I'm also wondering about the titles. Are they too big? Is the contrast too strong between Title, body text and comments?

An additional point here: when you quote a post in the comments, the quote font is just as large as the original post - ie. twice as big as the comment itself.

See this comment for an example.

I'm fine with the title size and the comment size as they are, but agree the quote font is too large... and think the quote box should have a colored background like it used to (I think it did anyway, light blue or something?) to make it more obviously stand out as being a quote when/if the font size is reduced.
