I can solve Wikipedia's woes quite easily - Wikipedia should limit itself to math, science, engineering, medicine, physics, chemistry, geography and other disciplines that are not at all in dispute.
Politics, history, religion and other topics of conversation that are matters of opinion, taste and state sponsored propaganda need to be off limits.
Its mission ought to be to provide a PhD level education in all technical fields, not engage in shortening historical events and/or opinions/preferences/beliefs down to a few pages and disputing which pages need to be left in or out. Let fools engage in that task on their own time.
