The fact that bitt and fact order, as well as which fact is displayed to the reader, is (or will soon be) subject to vote will provide a moderating influence, I hope.

The reason Wikipedia articles are often biased is that people in authority in the community simply do not respect the neutrality policy. Even if most Wikipedians and most readers would prefer things to be more balanced, those in de facto control of an article determine the article's degree of bias. If the wording and order of facts is determined by open public vote, my hypothesis is that there will be more of a moderating effect.

However it would depend on who is doing the voting. If you, for example, used Twitter to gauge political sentiment, you'd be representing x% of the majority position, which would introduce a selection bias that would imply that x% represent the views of everyone. The problems with Wikipedia for controversial topics Ali's that typically both sides are highly motivated to "win" whereas those that aren't so motivated probably have the correct answer.
