I'm currently learning more about Wikipedia for another course project, mostly focused on how I could use it to teach undergraduates. I've used Wikipedia countless times but never looked further into how the contribution process actually works, nor did I ever contribute anything. Below are a few brief observations about BLM on Wikipedia:
Every article has a "talk" page where users discuss changes. As events are unfolding, there are various discussions about the Black Lives Matter entry. For example: should there be separate entries for BLM as an organization and social movement (like Black Panther Party and Black Power Movement). Currently, COVID-19 is only mentioned once, in a sub-section on protest in New Zealand.
In addition to the talk page, there is an entire WikiProject, a sort of overview site to cover activity about BLM. Throughout June 2020, they are hosting an edit-a-thon to improve articles related to BLM, racism, racial justice, and policing.
Sidenote: there is also an entry for #AllLivesMatter – which according to the talk page was split off sometime in 2016. The "criticism" section opens with a reference to David Theo Goldberg (in our department here at UC Irvine).
As you can tell from my notes, I'm still very new (and slightly overwhelmed) by the different layers of participation. Since I will keep learning more, we could think about whether and if our own transnational project could contribute to discussions (see the WikiProject site for COVID-19).
