I wouldn t necessarily say they re backing wiki This seem a popular sentiment Wikipedia has a history and has gone on record to note that their articles are not based on fact They are based on the most common belief Granted there are cases where facts and common belief is one and the same it s too bad Wikipedia does not stick to facts We sure could use an online wiki that does that The fundamental reason why people feel something like wiki is useful is the quality of the summary NOT because someone said something once Quality summaries are written by people who know what they re talking about vs random collections of heresay It s only a happy coincidence that there are more people who know what they re talking about motivated to write about it than there are those who believe random collections of heresay is valuable and whatnot
