https://davidbisset.social update: success… I almost think i've gone as far as I can go with archiving tweets.
Thanks to Puppeteer and Browsershot I automatically take a screenshot of my tweet in case Twitter blocks embeds or goes down completely. My own personal Wayback Machine, kinda (don't know yet how to visit each tweet page automatically to generate the screenshot).
Might do this for #Mastodon and other social sites.
