I just want to point out that Piefed has skyrocketed in users this year. When you look at users active (comment, vote, or post) in a given month, you're talking about 7k Piefed users vs 35k Lemmy users. Along with Mbin's 1k MAU, that makes 7k/43k or about 16% of active Threadiverse users are on Piefed.
I'm only saying this to point out how awesome Piefed has done at attracting and retaining users this past year, going up from 1700 to over 7000 in 12 months. Lemmy lost 2k MAU in that time, so overall the Threadiverse is growing 🙂
