I disagree that the articles would not be of higher quality. It's not a matter of quantity over quality. I think, if proponents of a particular truth are allowed free control over their version of the truth, their passion for their version of things, to make their case and convince other people, will make for a better article. Articles that purport to be neutral, or take all sides into account, tend to be mushy overviews. Also, the multiple concurrent versions does allow for the creation of articles that claim to be neutral.
Furthermore, wikipedia is not necessarily a collaborative project. It seems to work best when people collaborate, but they don't always -- there are edit wars, trolling, grafitti, etc. The current wikipedia loses out from non-collaboration -- there is wasted person-hours in clean up, reversion, and the most damning of all, loss of public confidence. My proposal is allows for both collaboration and disagreement to enrich the project. _______________________________________________
You appear to be claiming that Wikipedia should become a place to prove a point. I'm sure theres a page called [[Wikipedia:Don't disrupt Wikipedia to prove a point]], and by replacing disrupt with use, you get the same concept. Wikipedia isn't a place for persuading people that your conspiracy theories are correct, and by "allowing free control to people over their version of the truth" and improving articles by "their passion to convince people that they are right" won't improve things at all.
