@Mtt Did the same some time ago. I usually go through my social network account usages yearly and drop those that I don’t use anymore (or use very little). Some are harder to drop, even if their engagement are poor. Some for historical (mostly nostalgic reasons), some for the fact that I have enough following on those to make them feel “important”.
I’ve been hoping that ActivityPub would solve this multiple account problem, but in all honesty, I just don’t see that happening yet. Most of the ActivityPub supporting socials are quite niche still. Curious to see if Threads boosts the adoption more or not on the big picture (if/once they start supporting it, as they’ve promised in their roadmap talks).
