Saw several links to this article on Facebook deliberately ignoring the fact that people present their identity differently to different groups (family, friends, work, interest-based groups, etc.) & how that impacts social interaction. https://boingboing.net/2018/01/22/facebook-is-sad.html
It got me thinking about exploring other Mastodon instances again, and an article I read ages ago on a contextual identity project at Mozilla. Looks like I should check out Firefox Containers. https://wiki.mozilla.org/Security/Contextual_Identity_Project/Containers
