I've been kicking around ideas for such a system, and am curious about prior art. I can't find anything solid on Google, but I think it more likely that I'm using the wrong search terms than that I'm the first one to have this idea. Does anyone here know of such a system?
I was thinking around decision software that managed decisions based on different models. using permissions and each groups model. some would be unanimous decisions, some would be majority, super majority, rank options, single approver. there would be a discussion section where pros, cons etc are discussed for each decision.
Yep, it's a very specific way of doing things, but to be fair it works and most attempts (there were lots in the late 90s and early 2000s) really didn't.
You'll find that real time editing by multiple parties without some strict controls and defined stages, usually ends up like a terrible mess.
The main reason Wiki works is that there are strict guidelines and/or the topic is well defined in the title of the article. With posts that is not generally the case.
An interesting approach is that of RapGenius. See: news.rapgenius.com/Satoshi-nakamoto-bitcoin-a-peer-to-peer-electronic-cash-system-annotated
You can see how would such a system work or fail to work, and its limitations.
