I actually started on Kbin.social, but then it got shut down, Kbin died and now fedia.io seems to be the largest one running MBin. I like the interface on MBin and I guess it’s good to have a diverse fediverse with different services, but at the same time, why use mbin when everyone congregates on lemmy instances? The local magazines on fedia are for the most part, quite dead, when compared to lemmy collections. In the end I feel like there aren’t enough people to go around to support many more services like MBin and Piefed.
If those options are functional, otherwise focus on making some of them functional.
There is definitely a LOT of half ass activity pub projects floating around. Everyone wants to start a new thing, but few people want to mature and maintain something someone else started.
We need more people doing the latter. We don’t need another half-finished client. We have those in spades.
