Ripster

Some engineers spent years of their careers studying this problem. How long did it take you to reach the conclusion that it is not viable?

This idea has been around since the 50's under various forms and will someday change the world as we know it. It is mostly known as Personal Rapid transit (PRT) and can be used to trasport food, waste, and all sorts of cargo including people at 1/2 of the cost of any other transport system (bikes can be cheaper). See www.personalrapidtransport.com (not a commercial site, just advocacy).

That is exactly what it is. Voted.

I have type I diabetes.

"Weissman implied that the pharmaceutical companies had put profit over principle, preferring to keep diabetes sufferers dependent on costly insulin than to cure them once and for all."

This is not fun.

I wonder when are we going to agree that you cant make business out of anything.

I see your point, and agree, well said, but not all social networks/web apps should aspire to be the next Facebook, some of them should try to do something different, not necessarily for the masses.

I am not that impressed. It is still very inflexible. The one social network that no-one has really not heard about is NotePub, and that is also the one that gets it right, you can just define custom groups of people and can specify for every bit of information which persons and/or groups can see that info.
