I was pretty much required to use Facebook for our sporting organization who have become so dependent on it that they could not function at all without it. I lasted three weeks; people's intelligence seems to plummet, language is almost unintelligible and the things people post on public forums is just plain scary. And this was supposed to be a professional organization... After that, deleted my account and will never venture near Facebook again.
That advertising is broken too. I was looking to buy a computer desk. I started getting hundreds of ads a day for everything from dishwashers to makeup and even men's hygiene products
