@congressedits turned up one of the more interesting edits from the House of Representatives today:
If you follow the link in the tweet and go and look at the edit you can see that this text was removed (emphasis mine):
Alabama Senator Jeff Sessions has been nominated, as of January 2017, to succeed Loretta Lynch as the 84th Attorney General of the United States. Dana J. Boente of Virginia was appointed on January 30, 2017 to serve as acting Attorney General. The first acting Attorney General under President Trump – Sally Yates – was dismissed by Trump after Yates told justice department lawyers not to defend his executive order restricting entry for people from seven countries. Sessions was confirmed by the Senate on February 8, 2017.
In case you were wondering what the rationale for the edit was they boldly stated:
Then three minutes later another anonymous user reverted the change saying:
The thing that I find interesting here is that the person who reverted the edit clearly knew the user was accessing Wikipedia from the US House of Representatives.
Now it's possible that they found out by some other means, but I think it's likely that they found out from @congressedits itself. Maybe someone else would have noticed the edit independently, but it's significant how the provenance of this edit mattered.
I think it's a great example of how social media can work to establish and maintain facts rather than just be a mechanism for spreading alternate facts and so called fake news.
