What did they do now? Is this about a theme or the site?

I hated it when they switched to that light blue frame and keep pushing you back to it instead of letting you stay in the WP Admin view; I think if you host your own site you can still stick to just the admin view, though. That still seems somewhat unchanged though.

I still remember when Evernote was a nice note-taking platform... then they made it pale green and search-based instead of tree-based and I haven't wanted to use it since.
