Providing value.
I'll be honest. I never understand why people get so excited when a company announces it's looking for funding. To me, if you are looking for funding after a product has launched, it just seems backwards. After all, if your product was good, it wouldn't need funding after it launched.
I guess the idea with this is you need to spend a lot to bring it to a point where it's profitable. Google is an example where profit really couldn't exist until it grew large enough, and it couldn't really grow large enough without money, etc. Facebook is the same way. Twitter, too (Okay, does Twitter actually make money? Is it in the black?). But all these things focus on making money via advertising.
Anyways, enough of my useless questions. It was a good read.
