The problem to federation is that there is at least some complexity to subscribing to other communities - at least right now. I love it here, but I have to be honest, it is a bit difficult to navigate for most.
But perhaps we're missing the point? What if we should be trying to sell the local aspect harder?
There is a demand for hyper-local networks as evidenced by Nextdoor. Couple this with an increase in people wanting to have a better digital commons - one not controlled by a single corporation.
For my instance tucson.social, I'm going to get some signs printed and do some local advertising. Pretty sure if I sneak some signs around the U of A campus, but mostly in public spaces where it's legal and proper.
I think that the local nature of all of this makes advertising a bit more effective and locally relevant. I don't want to sell it as a "reddit" but as another "place" that will exist whether or not reddit does (due to the non-profit or whatever other org we construct) to talk about our city.
At the same time I do this, I want to reach out to important community members to see if they might be interested in donating once I have a formal non-profit. I'd make sure to emphasize the utility such a site might have to local businesses once advertising is possible.
I have no idea if this will all work, but it's something I'm trying to do anyways. I just believe communities should be local, and that the online representation of them is as close to a mirror of the local one as possible. I also want to foster conversations that help people grow and connect.
So maybe, one of the admins here sees this, because I'd really like to join forces in a more meaningful way and hopefully gain the ability to deliver a meaningful experience to all sorts of communities. My immediate skills are technical, and perhaps if I follow along and learn your tips along the way, I can have the best possible chance of making this happen - and constructing the blueprints for others to follow.
I'm also open to other wisdom from the beehaw community! Have you done local marketing and advertising? I could use some tips. Have you formed a non-profit before? I'd definitely like to hear from you! Are you in Tucson and want to get more deeply involved? - dm me!
The only thing I'd prefer not to hear is how difficult it is. I'm fully aware that I've chosen to go all in on terrible odds. I don't really care anymore. lol
We've had a lot of success with that model on mastodon, as well as the sort of hub-and-spoke model where you have a larger instance (like beehaw) and a number of smaller instances that primarily interact with the larger instance and with each other. Location specific instances are also great for discussion, for telling people about events in their area, etc.
You could always start pretty small - basically if you could get enough people who want to have a Tuscon-specific community and who can be active, you could start a solid community, and probably survive off of relatively small donations at first. Once you've got a solid seed community it could be easier to grow from there.
I personally run (with a friend) a mastodon instance which is only for me and people we know IRL. While it's not what you want in the long term, it could be a good starting place while you figure out how to get everything set up and figure out how many resources you'll need and what funding you'd need. That way you don't have to solve every problem at once - you can open it up more once you're sure you have a solid foundation.
