Should online communities require accounts? @makoshark & @aaronshaw provide an answer in a new paper that was recently published in the journal Communication Research.
We've put together a short video (below) and blog post (https://blog.communitydata.science/the-hidden-costs-of-requiring-accounts/) that summarize the work.
The paper is online at https://doi.org/10.1177/0093650220910345 (paywalled...) and in preprint form at https://mako.cc/academic/hill_shaw-hidden_costs_of_requiring_accounts-PREPRINT.pdf (online for everyone).
We've also put full replication material (code and data) online for to ensure the work is replicable. https://doi.org/10.7910/DVN/CLSFKX
The paper has been a long time coming and you may have been seen it presented at various places or in earlier versions online or with the journal. @WikiResearch and @tilmanbayer did a write-up a couple months ago. https://en.wikipedia.org/wiki/Wikipedia:Wikipedia_Signpost/2021-08-29/Recent_research It's a nice summary!
