In gigaom, there is an article with a particularly bad heading.http://gigaom.com/2011/06/15/bitcoin-virtual-currency-may-be-the-worst-of-both-worlds/
I left this comment on the same.
The writer didn't understand that two sentences in this article right after one another, contradict each other.
"The system is setup as to reward early adopters"
"Because Bitcoin is completely decentralized, no one is completely invested in the long-term success of the system"
The early adopters are not rewarded with usable cash or wealth. They are rewarded with BITCOINS, nothing more and nothing less. These bitcoins maintain value if and only if there is a community around them, using them. The early adopters are the ones with the maximum incentive to keep bitcoins valueable, developing the community and clients.
This makes the bitcoin community structure more similar to that of a startup than a pyramid scheme. It might be the first structure of this kind in the world, melting together aspects of startups and open source. It might be a one-off, It might be a new way of doing things. The point is nobody knows as of now.
Criticism is good for strengthening bitcoin, but please concentrate on valid criticisms.
