Save your media!
If you create media, share it in more than one place! Keep records of what you have posted. Keep contact with people, real people, in person people, not just online. Do not limit yourself to one walled garden, or two, or even three. Because someday each one will close. And your work, your vital perspective which we all need, will close down unless you save it. Some will be lost; God knows and He understands. We humans cannot save everything. But we can choose what to save first.
