Dearie me! I've recently discovered Flarum and I must say—what an absolute joy!
I originally installed Discourse (because it's the hyped popular choice) for research collaboration a few days ago but it was slow, resource-heavy, cluttered, and the UI was terrible, so I started looking for alternatives and Flarum has won me over despite the let's say ‘recreational development’ and beta status. It's a shame you guys don't have commercial backing because you're obviously brilliant developers working on a product with a huge potential to pay for itself. So many great ideas and improvements over Discourse and NodeBB while keeping it all lightweight and swift.
Many thanks for your work, contribution to open source, and best of luck in the future! I'm looking forward to the future of this project!
