Look at all you facebook haters lol, its just a tool, its YOUR problem if you cant control it. Its like swearing never to use a hammer again because you missed a nail once.
I think that's a flawed comparison, at least for some people it has a negative impact (as opposed to simply not being useful enough as a tool).
I've actually derived a lot of value from Facebook in the time that I've had it, but I left as an experiment with my mental health and it's genuinely helped me.
Also, not being able to control it is hard to blame on the end-user when Facebook designs aggressively around engagement and hooking users in by virtue of psychology.
