I certainly can't argue with the above logic especially when looking at all the press lately. I have both a FB and LI account and use them every week for different reasons. I don't install any social networking app on my phone however- I keep that bare bones as possible.. I guess if "they" want to see what I'm doing, then go right ahead. I'm pretty boring that way I guess. Also, if you are currently carrying a phone and own a PC, anything anyone (with the means of course) wants to know about you plus some is already out there. I guess you can try and limit it, but unless you are off the grid, we (our actions, history, browsing etc) pretty much are visible anyway. Just stinks that people would mine our personal data for their own monetary gain. Disappointing but not surprising.
