I've never had any problems with Facebook. As far as them selling my info, Google does too. Google actually tracks my info. Recently, I had to reformat my PC. I did a couple of web searches on something I searched BEFORE I reformatted it and Google still had the link as purple (showing I'd been to that link before). I was like, "WTH?!?!?!?" It has worked to my benefit, though. Many websites sell personal info, even internet vendors and also credit card companies. I'm just very careful as to what info I put on Facebook. Just remember, if you don't want it on the internet, don't post it ANYWHERE!!!
For those who don't like the timeline, there's a Facebook add-on called, "Social Optimizer". It's makes FB appear more like the old Facebook.
