There is oversight in Wikipedia to help prevent untruths from being published there. It isn't a total free-for-all, but runs in a somewhat decentralized manner like the Steem blockchain runs. Just as we have Blockchain Engineers, developers, and SteemCleaners, there is a Wikipedia Foundation that helps ensure the integrity and success of the project. There are various levels of editors that check work, make corrections, and ban people that try to run ripshod through the process.

It is very disturbing to me when avid proponents of the decentralized nature of the Steem blockchain denigrate other decentralized projects like Wikipedia. I have seen this happen over-and-over, though. I really like having a dynamic, up-to-date encyclopedia online rather than having to rely on a centralized, for-profit company like Brittanica or Funk & Wagnalls to publish their once-per-decade hardbound encyclopedia that only contain articles from their "experts" in each field.

I have been a contributing editor at Wikipedia since 2006, and always keep my eye peeled for inaccuracies and make corrections when I am certain I have spotted one. I am very proud of what Wikipedia has built, just as I am proud of what the Steem blockchain has built.
