Own your words, my friends. Backup your words. Donโ€™t put them into walled gardens that may grow weeds and disappear. https://www.hanselman.com/blog/your-words-are-wasted (2012)
Your words are wasted

It needs to be said again, perhaps this time more strongly. Your Blog is The ...

@shanselman agreed though I'm far less concerned with my tweets and toots, more about the longer form content like blog posts.

When some blog posts are built upon weeks of R&D, you really don't want to be locking that up.

Own the canonical, syndicate far!

@turnerj @shanselman yip agreed, don't care to much about my social posts, but indeed my longer written words, which is why I switched back to self-hosted on own domain from Medium, some times cross-post but import to correctly reference original content.
But important to think about the legacy of your words, choose a license so there can be no mistake of your will. I've chosen CC BY 4.0 for my personal content, just as I've chosen MIT for my code.
