Does joining a small instance affect your reach?

Will less people see your posts if you self-host your own instance?

No and no.

On my small single-user instance (atomicpoet.org), I sent this post 2 hours ago. As you can see, it now has:

* 784 boosts
* 354 favorites
* Too many replies for me to count

As I've now shown, size of an instance is no obstacle to spreading your message!

And within 10 minutes, that post now has 926 boosts, 412 favorites.

Again -- this is a self-hosted instance. There's no reach disadvantage.

Also worth mentioning my follower count is low.

@atomicpoet It's actually the other way even, with smaller instances, more people will see you on local timeline, so more chances of boosts!
