re: Facebook longterm viability question

The answer is that the BS isn't really hurting facebook. I still have mine but haven't actually scanned the newsfeed in years, and will go months without opening the app. I use it solely to coordinate things with friends out of state, and it allows me to do that. I'd wager there are plenty of folks in the same boat as me, and they don't have any plans to delete. Bottom line is that the BS is optional, but its still a decently useful tool.
