I am forever grateful to him for building & popularizing Mastodon, but I don't think @Gargron should be working on features at all right now.

Instead, he and the Mastodon non-profit (and a whole bunch of others) should be figuring out governance for collectively making decisions about Mastodon. Features in the Fediverse shouldn't be up to one guy, or even one company.

That's the whole point of the Fediverse. We do this together, or not at all.
