I don't complain about FB making my info public, as I have never chosen to share any with them. However, I've been told on this site more than once that over-30's "don't get" Facebook and should ask young people to explain it to them, and should refrain from even making comments about FB. So I find it a little amusing that one of the reasons I may not get it is because I am not a "dumb fuck". Regardless of the comment's provenance, I smiled when I heard it.
