Very cool! If you want to post a link or message me, I'd love to check out your gemlog. I thought this piece was really interesting.
I'm just getting into self hosting, and the "storage waste" of all this duplicated content has been on my mind a lot, but I hadn't really considered the energy costs or the feasibility for folks with data caps, slow Internet connections, and so on.
I absolutely love the idea of federated applications. It would be great if they someday became the dominant way of running things. But, even if we could get every user interested, I haven't really put in enough thought or research to know whether running these applications at huge scales would be feasible or desirable. It's great to see folks talking about the problems we'll run into and how we can be better than current big tech companies about considering the impact of our choices.
Anyway, thanks for the well-written and insightful piece.
