I think it's fine, people just need a bit of time to get used to it. Whenever pages change it takes me a while to get used to it, but in a little while I'll forget what it used to look like!
Although it did take me about 5 mins to find the link to the forum... and I didn't spot where the newspost was for a while either! But Jeph has said before that you should read the comic first, so that helps do that, my eyes always seemed to drift over to it and spoil it (if there was a spoiler in it). I quite like the brown colour, it's soothing. But that might just be me!
