Facebook and Pandora--both--on the same day?

What is this about? What's with both Facebook and Pandora making changes--in the case of Facebook, big changes--on the same day? At least Pandora's is appealing. Facebook, in the meantime, is confusing, at least, still has the same ugly, ugly sign-in page and what you're looking at keeps flipping up to the top WHILE YOU'RE READING so you can never remain stationary. It should do wonders for being, having and attaining attention deficit disorders. So it goes. One thing about computers and all thing on the web, nothing will remain the same for very long.
