What certainly seems to be the biggest qualm over Wikipedia is its lack of credibility -- anyone can contribute, which brings advantages and disadvantages, the latter being false or misleading information, or just plain nonsense.
This has been on the rise lately, and the Wikimedia Foundation (the site's organisers) are considering mending this problem with some changes. The proposition, dubbed 'Flagged Response', is essentially an approval system whereby non-established users will see their contributions pending, to be approved by users who have been around for longer and have proven credibility. These users will be able to make instant changes to the site, too.
“[Instances of misinformation] could [...] have been prevented by protection or semi-protection, but [..] [many are] breaking news [stories] and we want people to be able to participate (so protection is out) and even to participate in good faith for the first time ever (so semi-protection is out)," said co-founder Jimmy Wales.
On the German version of Wikipedia, the system is being tried now, where it can take up to three weeks for edits to go live -- the obvious disadvantage at this point. However Wales says this could be brought down to a week or less if adopted entirely, and if it did not apply to all entries.
Though according to a community poll 60% of users are in favor as of now, many others are angry about the proposed changes. In response, Wales has sent out a call for alternative proposals, due within 7 days, which will then be voted on by the membership for 14 days thereafter.
“Those who are in the minority who are opposed to this are invited to make an alternative proposal within the next 7 days, to be voted upon for the next 14 days after that, a proposal which is clearly aware that you are in the minority and that does not attempt to simply re-hold the same vote,” he said.
“I ask you to seek some detailed policy around the use of the feature that you think both you and the supporters can agree upon. Simply engaging in FUD and screaming is not going to be helpful, but I trust that outside of a few, most of the people opposed can actually work cogently with others to find a reasonable and responsible compromise position.”
(Don't worry, I don't pointlessly believe everything on every website. I usually will see something, then look for it on alternative sources)
