It's often assumed that because Twitter has a larger userbase than the Fediverse, that accounts would automatically get more followers there.
However, many accounts (especially FOSS projects) have more followers here on the Fediverse.
Some examples (as of 26th July 2021):
@fdroidorg has 10.8k vs 7.33k on Twitter
@k9mail has 1.57k vs 680 on Twitter
@Minetest has 1.39k vs 785 on Twitter
If you know any Libre projects that are yet to join the Fedi, please ask them to give it a go!
@josias @FediFollows With Twitter I have this "Shout into the Void"-Feeling.
If I post something, no one reacts to it.
On Twitter I only had a few contacts, mostly people I knew.
I think the fact that I didn't know anyone at first, so I was more open. I just explored and if someone posts something I find interesting, I follow them.
