Very clear and clean - the colour scheme is clearer, without the slight "fog" of background. A very friendly amendment.
I'm someone who finds that "new" does not always equate with "improved". This is one of the finest, simply set-out sites to come to terms with, and far easier to deal with than many others.
Possibly the typefaces used may be modified, but there's nothing wrong with straightforward sans-serif faces for smallish bunches of text.
I've found that if I want to italicise something and underline it at the same time, that's a bit problematic, but that's unimportant.
Please don't OVER change what works so well. I'm sure you know at which point to stop, before "change for change's sake" happens.
