I don’t want to move educators. I’d like to spread the understanding that platforms that you pay for with your attention, and then that attention is manipulated, may not be the best place to direct our pupils data and attention.
A start along that path might be to think of a blog that you either own and control or is owned by a benevolent entity (Scot Gov in this case) is the best place to store your data, memories etc. From there, they can be sent out to social networks.
Ideally, IMO, there would be a benevolent network or system that would eventually work well enough to replace commercial but free, services.
