Jason C. Nails it.  Total bullshit move by Facebook. Simply put:

1. your site was for me and my friends - not the world - and you just by default changed everything to the world

2. shady shady shady - by default changed everything so all users have to spend 10 minutes  changing setting “back” to why they joined the site.

3.  plenty of sites resort to tricks all the time - hell at my last company we did it a bit too..of course we had 1,000,000 members not 300,000,000 there is no reason for that type of move

4. i’m a 4 time venture backed ceo. it took me 3 times to figure out what i had to change and i blew off the rather vauge roadblock message.  these types of quantum changes should be blasted in users faces.

bottom line - fucking shady. cheesey move. you guys should be embarassed and without question have jumped the shark.  how can “do no evil’ people from google running the place believe this is the right thing to do.  nice move. i hope the kids revolt and kill the brand.
