I appreciate your candor regarding the (un)sustainability of social media platforms. As a filthy heathen free user of this platform, I realize I am part of the immediate financial problem, though as you've pointed out, that seems to be the case regardless of where we go or what we use. CoHost's model may be the least abusive of the user, but it could be argued that it's one of the more harmful models to the owners (which really isn't appreciated for the sacrifice that it is. Seriously, thank you for sacrificing your sanity and health so that a lot of us have a little breathing room on where to go or what to do next).
If I might put on my infrastructure hat for a bit (CorpoInfra Dinosaur here), you mentioned a pivot to a model similar to Panic, wherein you publish something for others and take a slice of the pie. I think that's not far off base for what CoHost could try, and something that seems either entirely unavailable or locked behind XaaS subscriptions: self-hosting.
A large gripe I have in the era of the modern internet is that self-hosting your own web presence on a Raspberry Pi or NAS is an overly complicated pain in the rear. You need your web server (NGINX or Apache? Or something crazier?), and the underlying OS (Linux? Windows? OS/2 Warp? Solaris?), and the load balancer, and the relational database, and you have to configure them all to talk to each other after installation unless you use containers, in which case they may talk to each other but now you also need an ingress controller into that subnet unless you're running Kubernetes in which case-
You get the idea. Pain in the rear, and definitely not for Joe Average.
But what if this was already bundled up, tied off with a nice bow, and as easy to deploy as an app or software package? What if it came with the same familiar tools as CoHost? The short term proposition could be a one-time purchase of, say, ~$100 that includes a year of support and updates, or maybe the ability to "hook" into the CoHost CDN and Firewall for hosting on a standard residential ISP. Almost like CH+, but on your own machine, in your own home, that you own. Then CH+ could cover another year of updates and CDN/Firewall access, if you so choose. Or not, if that's not viable from a financial perspective. Or maybe you sell support tiers for professional users who need help with it. I dunno, I'm an infrastructure dinosaur, not a business guru.
For a fossil like myself who grew up Telnetting over to NCSA and uploading my horrific webpage one line of HTML at a time, the prospect of a solution that's easy to deploy, use, and maintain is one I've lamented for since my first community implosion in the 2000s. Something I'm not paying a hosting provider gobs of money for dedicated server time, when all they do is reuse FOSS packages and never donate to the underlying projects.
That's just my two cents. A Panic-style revenue model where I can buy a CoHost container/package/ISO, throw it onto a RPi or Container engine, and either manually port forward on my router/domain name or hook into a CDN + Firewall would be a dream come true. The important part to me is a basic web presence that's easy to use and maintain, which CoHost certainly is.
Again, thanks for the transparency on finances and your efforts thus far. Whatever happens next, I appreciate your attempts to build something better.
