The website was just redesigned, some kinks are being worked out, if you see anything that looks weird please continue to let us know.
How did you get the /blog link? did you just type it in, or did a button on the website link you to it? The content there is exactly the same as the content on myspace and on the old blog link with the old website colors. The content is not going to be affected, just the website design/colors.
If you go to amandapalmer.net and click "blog" in the top navigation bar, it takes you to blog.amandapalmer.net - which is still active, up to date and should be the page you use to post comments to (unless you want to post comments to myspace).
