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.
I was a frequent Kbin.social user and I miss it. But also, you have to move on when the end is reached for the foreseeable future. One of the strengths of the Fediverse, is that you can make an account on something like MBin and still interact with Lemmy instances as if you were registered on Lemmy. Anything that makes me use one account and supports cross-platform is a major plus in my book.
Oh and uh maybe some of those running Lemmy, i.e mods, are kind of scummy so I don’t want to be at their mercy if I was just registered to Lemmy.
