We (people in general) can't really expect the Fediverse to "kick off totally". A community is only as good as its content; if everybody waits it, it won't kick off. Depending on the nature of your content, it might be useful to dump the content in the Fediverse alternative of your choice, it'll get a premium spotlight so it's good for you, too.
(I'm currently doing this, with my conlanging content. There's a lot of trash, so I need to sort it out first.)
