First, the rolled out a new app that allows users to find the physical location of other users near them. People see this as a perfect tool for stalkers, and frankly, considering my experiences with certain parties via the web, I would NOT want Facebook tracking my every move, regardless of how they'd think to accomplish it. I actually spent a couple of vacations back in 2006, worrying that I might have a certain someone pop up to try and discuss religion with me... I'd hate to think Facebook might help someone do that.
Second, they switched all users' primary contact addresses to internal "@Facebook.com" mailboxes.
This seems to fit a pattern that has bothered me about them from the get-go: they decide what features to add to their site seemingly via an internal bull session process, and they roll them out without bothering to check to see how the users might like it or not. And really, any company that doesn't care what their customers want should not get support... but you have to recall WHO Facebook's "customers" are: it's the companies that use Facebook data for marketing processes. NOT the users. I have very little interest in "being social" on-line if it means that someone is going to parse through my social interactions in order to glean information that I would prefer to keep private.
Why so many people want to keep details of their lives stored on some company's computers for just anyone to hack into and rummage through, I can't begin to fathom... but apparently, there's millions to be made in that "industry."
Not only do I not get it... I don't WANT to get it.
