So alright - We've got a LOT of problems that need to be addressed - Environmental problems, Social problems, Cultural problems, you name it. To make things worse, these problems are all tangled up, meaning that in order to solve one, you frequently need to at least make inroads on several others, and a solution to one might actually end up exacerbating another if you're not careful.
As such, we need more than individual solutions. We need a system for developing lots of cohesive solutions, while considering all relevant problems, and for applying these solutions on a large scale. It's gonna be quite a challenge. Right now, the only things that come close to being able to do this are governments, and unfortunately most of those can be counted squarely on the "problem" side of this equation. So obviously, we're going to need to look elsewhere for coordination. Luckily, I have an idea.
You've possibly seen me ranting about this elsewhere on the forum, but I'll repeat: It's a project of mine called Agora, you can find it in my sig. It's basically a new kind of internet forum, designed to allow large numbers of people to talk about complicated subjects without the conversation crushing itself under it's own weight, like it would on a traditional forum. Instead of linear threads, posts can be in response to any number of other posts, and can have any number of other posts in response to them. As such, the forum assumes a web structure. This, in concert with a system for ranking posts, means that the conversation can split and converge to cover all relevant topics, and that replies that contribute more to the conversation will be more highly ranked, while those that contribute less will be lower ranked. This means that a lot more people can contribute to the conversation, and that it's a lot easier for newcomers to catch up to the conversation - They need only read the posts in their direct conversational line, and can ignore the rest, while in a traditional forum they'd have to read pages & pages, only a small fraction of the posts on which are relevant to any given pat of the conversation.
This is of course merely a tool for communication, and only a beginning, at that. There are loads and loads of problems that'll need to be solved, but I think it'll give us a step up.
