Those type of comments always make me laugh

You use it how you want to use it.
Those who advertise every aspect of their lives on it , well that wouldn't be any different on any website.
What's annoying about it is the incredible banal and trivial crap that some post, and I'm not talking kids, some are grandparent age!
But you take from anything what you want and leave the rest. If it's not your thing you just don't touch it at all, same as if you hate certain hamburgers

Many love 'em, many don't.
