Not really a fan of the new color scheme, but I wasn't really a fan of the old color scheme either. So, I'm sure I'll get used to it again. Add one more voice to the chorus of "can we get a dark theme?" But all in all, it looks decent.
I'll also agree that the header section looks a little oddly sized & empty. Aesthetically, you can tell the BARF logo wasn't designed for the current look. Also, the ad section looks a bit unbalanced too. Like it could be smaller and maybe would look better with a thin border or something?
The page counter at the bottom of the posts, it says you're on Page 4 of 4, but didn't the classic site also have the page that you were looking at in a different font or color? That isn't carried over into this version. A tiny thing, but a thing I noticed.
Any slight negatives on the desktop site are far outweighed by the improvements to the mobile site. I'm sorry, but the old mobile site was terrible and it's awesome to see it updated.
All that said, really appreciate what you guys are doing behind the scenes.
