Compare this to a traditional investment fund where you hand over your money to a private organization with opaque investment strategies, business operations, and technology. If I invest in a Vanguard or Fidelity fund, they only report back what is required of them by regulators. They take little to no input from investors, and may be running their business on decades old technology filled with flaws and bugs.
I view the DAO as an open source investment fund in the same spirit as "The Cathedral and The Bazaar". It's not perfect, it's messy, some people are more influential than others, there's a lot of noise, and it could collapse on itself at any time. But everyone gets to participate (for better or worse). Lots of eyeballs are constantly watching, and plenty of concerns will be voiced.
I know the HN crowd is a skeptical one, but try to keep an open mind. This could grow into something great. And if it doesn't... hey, it's not your money, so don't sweat it.
