I'm on the side of no long term value.
(Not to mention that even if it is long term can it be profitable.)
The reason I think "no long term" is that in it's current incarnation it doesn't hold value for "normals" other than people who want to follow celebrities or of course the tech crowd. Or are obsessed with knowing the moment there is an earthquake on another continent. That's essentially entertainment. It's not something you need to know (in masses of course there could be individuals that need to monitor those things.)
I mean sure it is useful to be notified of some event that happens but personally I don't think the need for that is greater than the current alternatives of getting that information (or that a better way to get that information wouldn't be developed).
Most employed people with "regular" jobs are not all obsessed with twitter and the information that it delivers.
Netflix, otoh, delivers a product that people have received for many years by a better method. And the money making part is baked right into the product.
