I installed a plug-in that shows me how long I've spent today on selected websites, but instead of causing me to minimize social media time, it's just caused me to try and make sure I spend more time on Mastodon than on FB 😂
(Which unfortunately has been a complete failure. Facebook still has way more content, which I've curated one way or another over almost a decade, and it's full of psychological tricks to make time fly and keep me engaged longer than I intended on.)
