Andros Fenollosa on why we want small systems instead of decentralized ones when talking about online communities.
There are no commercial interests and people know each other. It’s like a shoe shop in a small town. The shop can only serve a few customers because there is little space, you know the owner’s name (maybe even his wife’s) and the shelves don’t offer much variety; and yet you know you will be well served and the owner wants you to leave with what is best for you.
