I wasn’t using Mastodon much, so I redirected my standalone account to the Micro.blog-Mastodon-Compatible one. One less social network to check. For now, I still have Threads and Bluesky, both barely used. I may phase them out soon as well.
Torb Might do the same myself. I can follow Mastodon people from mb anyway (with nicer more quiet interface).
As for Bluesky: I just set up my Micro.blog to automatically post my posts to there as well and then I check it from time to time.
Juha Liikala 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).

Matt Langford @torb @numericcitizen I am doing the same for Bluesky. Basically only check it when I see a notification.
Matt Langford @juha I would love for something to fully solve the multiple account problem, but I don’t see that happening. Too many things don’t translate properly between the different services to make it possible.
For now, simple cross posting is probably the best we’ll see. And obviously that’s not even fully working (Threads and Twitter/X).
Mitch Wagner I keep thinking that there must be some way to for micro.blog to remain micro.blog while fully supporting Mastodon.
Use the same address in both places, supporting boosts and favorites while on Mastodon but not while in the micro.blog universe.
I haven’t yet figured out how that might work.
