I really don't enjoy the thought of being famous, and especially not the ephemeral famous-on-the-internet variety. I especially hate the end results of how twitter gets used, and turn a blind eye to nearly everything that happens on that website. It's something of an abomination watching silly people cram their already dumbed-down thoughts into something even dumber than its natural incarnation.
Web 2.0 is really more of a 2004 idea (as with viral content which is even older) but I understand what you're driving at. Especially since some of the technology involved isn't all that new either, which points to the fact that the purchases are more often a form of conflict resolution between competing companies, than genuine success. Large companies purchasing smaller companies before they can become threatening.
There might be much physics-related publicity, but not too many drastic shifts in our understanding of the world that surrounds us. We still don't have any moon bases or martian colonies, and so maybe certain special bosons are the the seat of mass, enslaving us all to gravity, but until that discovery actually pays off, big deal.
Stocks are imaginary financial instruments, and publicly traded stocks are even more imaginary. Some people have a lot of imagination, I suppose. From what my friends tell me, owning a home is worse than owning a car. When your car breaks down, you have to walk home. But when your home breaks down, you're either cold, or wet, or both, and there's no place to sleep. At least, when you rent, there's someone else to blame.
