I hear what you're saying about only wanting the most "correct" version, and no doubt that's how most people feel when looking for information, but about some things you have an ability and perhaps an obligation to contribute to deciding what is the most correct version...

This suggests to me that Ward is onto something here, but also that you may have a point about it's limitations in its current form. I hope the hypothes.is project (funded by kickstarter, http://hypothes.is) succeeds, and I wonder if some degree of integration between the two is possible so that reputation and correctness rating across wiki-nodes (or any such federated system) can naturally "bubble up" to top visibility with some citation/indication of the bubbling via the hypothes.is client, regardless of which specific fork of the wiki you happen to be looking at... I'd love to discuss this possibility further with Ward, hypothes.is, or anyone else interested since they'll both be open source projects any of us can try to make this happen in :-)
