My experiments to share reprexes i.e. output from
reprex on Gist and on Twitter. For quick demos and show-off and for asking questions outside of platforms (e.g. not on a forum).
Gist is good because it has comments, compared to say sharing on Slack and threading.
Twitter is convenient for advertising a question or demo, in my opinion the perfect combo is nice screenshot + link to the online home of the code. I prefer an URL to a gist than to a Carbonate page.
