If we want people from the microblog fedi to participate we (collectively) need to up our moderation game. (And in my personal opinion instances like .world have grown too large to accomodate any reasonable expectation of moderation, except for select individual communities set up there)

Improved moderation tools would help, however are you familiar with the filtering/muting tools available on Mastodon/Firefish/Misskey? These, coupled with an ability by individual users to block entire instances, help relieve some of the need for more moderators to help by enabling individuals to essentially self-moderate/curate their experiences as desired.

I think both improved moderation and individual filtering/muting tools would help greatly both to encourage microblog folks to join in, and make the experience better for those already here.
