Speaking for myself, I like FB better because of all the other features it offers. I can "like" or join other interesting pages and therefore get interesting or fun posting in my news feed. Then my FB friends and I can share these postings back and forth with eachother. Nothing is totally private online any more, if ever. With FB we have the option of choosing our audience and therefore achieving a degree of "privacy" I find FB quite fun.
Ditto.
