Not on FB (or any other). I was briefly on it years ago after a couple people couldn't be bothered to email anymore, saying FB or nothing(!)) Gave it a number of months, but didn't like it and left. Lot of the same reasons others gave. #1, lack of real conversation. Privacy issues with the company. Also, I simply had nothing to say in that format. Found it boring.

At first I did creep around trying to find people from way back. But... 2 best friends from h.s. -- one wasn't on, and the other one never found. Really common name didn't help. I'd always worried about him because after losing touch, I'd heard he struggled with deep depressions. Nearly all my friends were guys, and figured their SOs might not appreciate my contacting them, lol. One of which I really struggled over contacting or not, as I'd later learned he has BP. But I never contacted any of them. We were all on the intellectual/success trajectory, but I'd crashed and burned early with undx'd BP, and didn't want to have to explain anything. Subsequent years, moved a lot, everyone at aquaintence level. Nothing to keep in touch over.
