Recently, @prnc tried including a Zoom link (actually a bit.ly shortened URL) in a Clojureverse post, and we did not experience any problems such as unwanted visitors.
(I think that is the main concern when sharing a link to public events – the risk that the whole internet will hear about it and join your meeting – it did happen in the past when we tweeted a link and was actually terrifying.)
So, it might be just fine to share Zoom links here, at least if these are not links that you use very often.
