I feel the same way myself. Everyone is on those things. I did open an account (not sure that’s the right term) with a fake name and no pics or details, because all my friends want to send pictures, etc.
Yes, it’s totally weird that people post such details (oftentimes, very trivial)…very weird. I’ve tried to understand the mentality, but really can’t grasp the appeal.
Now housing/economic/political blogs…that’s a whole ‘nother thing! 🙂
