I hear ya. I was on it for about 15 minutes like 5 years ago. the way I see it is other than being curious as to whatever happened to a couple of people from my long ago past I ave no use for it. People from my past that I want to be in contact with. I already am. And those I am not. I generally have a a reason to not deal with them. and those I have afore mentioned being curious about. I'm merely curious what happened to them. And not to strike up a new relationship with them.
In my 15 minutes I accomplished that and have never been back
