Emphasis on individual online space, so not a forum/federated platform, more like maybe a blog or portfolio or anything else more experimental. Suppose the full gamut of tech familiarity from unfamiliar to familiar.
Original Title:
What advice and cautionary tales would you give on setting up one’s own individual online space with today’s tools?
The same rules as everywhere online:
Nothing is anonymous and everything is permanent.
Don’t post anything you wouldn’t want read aloud at a Supreme Court hearing or Sunday dinner with the family.
