I'd contribute to the thirst traps to get everyone to come over but I don't think anyone wants to see a hairy overweight dude get nearly naked.

All networks start small. What happens upon seeding is we often find, increasingly interesting overlaps, someone, somewhere different, or someone different finds it. Because it's an open network, not a gate kept network, or at least more open. Over the long run, the fediverse will increase in population, and popularity, overtaking networks whose primary purpose is advertising and data collection. So yes, start small, try and see what happens. This is his we build sustainable networks, for the people, by the people.

and I quote you:

My favourite Band for example. They only use Instagram and Facebook. It's infuriating. I just log in via browser every few months.

How many others feel the same way? At the next concert you say, they've got another page, on an open source network, come check it out. You say you're a big fan, so why support them? Never failed, never tried.
