I would not. I am 44, so I remember what life was like pre-internet. I have considered how I have kept in touch with people over the years, what my relationships were like, what made me happy, all these things... and I have come to the conclusion that Facebook has been an almost completely negative experience across the board.
I have claimed my name, simply because it is a common one, and I don't want to be denied some future job because of something a namesake posted. That that is even a concern is a large part of what makes Facebook awful.
Now, all that being said- I still think that something like what we call social media today could be a positive experience. I just don't think any of the current platforms are there.
