My motto is, so long as I keep my general post quality up (in terms of trying to post only things I find genuinely interesting or worth checking out that are novel to the fediverse in some way) even if I post a ton it is a taunt to others to jump into the feed and make it so I don't determine the entire feed of communities. I don't control anything, I don't have special tools I use to post way more than humanely possible, I just post a lot.
If I can add such a big chunk to the fediverse though, than can it really be so hard to fight back against the overwhelming network effect of corporate social media? I am just one person, I don't use any bots, automated posting or anything and yet I have thousands and thousands of posts.
I am not saying spam communities, rather I intend to slap you in the face with my posting glove and challenge you to an interesting content duel to the last upvote.
En Garde!
