truekasun @luceos Not everyone wants to pay so much and host with ghost hosting. They are so costly. They charge for number of pageloads or something, when we can many times more pageloads even on a much cheaper VPS. They are many many faster hosting providers than what Ghost hosting service offers. Vanilla also has that same business model, but again very costly. I think that this pro/paid hosting business model of theirs will remain stagnant and not increase much unless they give reasonable prices and host on very fast hosts. Because nowadays people can host on any fast VPS or Cloud server of their own choice with the superfast serverpilot.io beginning from $5-10/month.
Wordpress.com (free with ads) and Medium (free with no ads) have more reasonable prices than Ghost, not based on monthly pageviews, so they are thriving somewhat. I think Flarum's present transparent donation-based system on opencollective has great potential to thrive a lot if more and more people install flarum once it is stable. There will be many more monthly backers. They will support it by donations as they themselves will be using it for their own bread and butter. The whole ecosystem will thrive when it is released as a stable version with frontend installation. Flarum just has to release a stable version with the slow search fix and if possible a related discussions extension (like discourse) imho.
Flarum has much much more than what Ghost will ever have to offer. With the Flarum's SEO extension, Flarum has on par SEO on Google like Wordpress. Ghost, etc. So Flarum can be used even as a blog. More so if someone makes a image-based blog-type home page layout extension. Communities have many more supporters and blogging platforms, other than the establised wordpress of course. So many more backers and donors will come forward for Flarum when it is stable imho.
