I hate to say it, but all the "changes" were actually just the inclusion of stuff their system tracks anyways. With a few clicks they can get a complete profile of any one of us. How much time we spend on our own page, whether we like pictures or reading profiles, how much time we spend on any given page, and even in some cases which sites we get to facebook by.
Myspace is worse.
People need to remember that for anything free, you're name is worth 100 bucks. This is the information age and information is more valuable than ever before thanks to computers.
Now, personally, I didn't like the changes because I felt like they made the interface sucky and didn't have options to gain "privacy". They seem to have fixed both of those so I'm back to being semi happy with facebook and jubilant that it's not anywhere near as sleezy and crappy as web 0.5 myspace.
