I feel this so hard in life... but also this particular community does make all of these interconnections between Fediverse products a very central point.

It's true that both Mbin and PieFed have far fewer users than Lemmy, in large part bc historically they both lacked an app, yet now both have at least provisional support from some app or another, so there may be many more users of them in the future. Just search this very post for e.g. fedia.io (an Mbin instance, possibly the largest one iirc) or PieFed.social and you'll see that these other, non-Lemmy members of the Threadiverse/Forumverse/Whatever part of the Fediverse are already here.:-)
