If you want a specialized device like a digital camera, then Facebook is not the place to look for advice from high school buddies, but for advice on what phone to buy, it could be. I asked my FB friends for advice on that very topic, and it was very helpful - and knowing the people giving the advice helped greatly because I was able to decide whose opinions to give weight to, and they knew my circumstances - they advised me on which phones are robust enough to withstand a toddler at home without me explicitly asking about that. Friend groups and the newsfeed do a good job of controlling awkward oversharing - I see updates mostly from people who I care about, and this seems to be constantly improving. This has added immensely to the value of Facebook for me, and a time saver. The effort Facebook puts into this is very valuable and certainly not a waste of resources.
