Thank you for all your thoughtful responses to my question about how to announce on commercial platforms that you are leaving.
I may keep my accounts deactivated… and EMAIL the people I want to keep in touch with instead. One big reason:
The opaque algorithms of Big Tech may hide my post, esp if it contains keywords like “leaving” and “find me here instead” with a link to an external site.
In my email, I will definitely boost the Fediverse and volunteer to help friends set up accounts here 🤗
