Mark Zuckerberg is trying to manufacture something similar at Facebook. And it's not going to work. Listen, I still love Facebook. I still think the stock will continue to soar. And there's no question the platform provides an incredibly effective place to advertise. That's only going to get better. But, I'm looking out over generations here. Thinking about my original thesis. When I'm about to die, I'll likely be sending my farewell wishes -- you know, a good 62-63 years from now (that would make me 100) -- via Twitter, not Facebook. Because, as the two social networks evolve, the latter doesn't look to have nearly enough staying power. That could change on a dime, but, in the moment, it looks like Zuckerberg made a poor strategic choice.
