ScienceBlogs has just redesigned the main site. Sort of. The change is subtle enough that you might not notice it-- the only real difference on the front page is that the "channel" list has been reorganized-- it's now slightly shorter, and some old channels have been combined into new ones.
There are two practical advantages to this: on the back end of things, this allows the individual bloggers to put a post in two channels at the same time, which is great for things that straddle the boundary between two areas. Also, the new channel pages feature pictures, with the Physical Science page currently graced by a picture of my lab, so that's a nice bonus.
There are presumably disadvantages as well. Here's a comment thread for you to complain about stuff in.
Well, I guess that explains the bug with certain blog posts appearing more than once on the ScienceBlogs main page, that I've noticed for the past day or two.
If you know who is in charge of the site software, tell them to email me at my contact address. They have significant security problem with the site and I have been completely unsuccessful in getting anyone at Seed to even reply when I used their public contact address to tell them about it (I've been trying for over a month).
If the goal is to give less information about what's in the various blogs today, it appears to work quite well.
