But really, I think one of the things that attracts users to Mastodon is how uncommercial it all is. The current audience explicitly does not want display advertising or a website full of #brands
My engagement is still low, but on Twitter I would post something and it would just never get seen. Now at least a couple of people will often reply.
I just set up a new Masto account on a larger server, started watching, following, engaging.
A small case in point: Rands In Repose blog's accounts on both platforms. 42K followers on Twitter and 7.7K followers on Mastodon. Despite Twitter having 5.45 times as many followers, Michael Lopp reports significantly higher engagement on Mastodon. Just had this conversation with him.
