The business world is littered with corpses period. 4 out of 5 non-restaurant businesses go under in the first 5 years (restaurants it’s even worse).
FB has 900 MILLION users world wide. 3 entire Americas. Even if they do start to falter it’ll take a long time for that to unwind. They’re at least a good midterm investment. Between advertising and game cash they actually get a pretty decent chunk of change per user. They have at least as good a revenue stream as google did when they IPOed.
They’ve never gotten a penny from me. Now they may have sold my personal info, but that’s a whole ‘nother story.....
