Got hooked on running my own forum software with PunBB back in 2004, then moved to FluxBB. Never cared for the heavier boards, the lightness of PunBB had spoiled me.
Flarum is bit different animal, I've been using it for just 2 days, still discovering new things.
Where I see Flarum fitting into my needs is for offloading commenting from my blog style sites. Since it doesn't fit the block structure of a traditional forum, embedding a discussion should not be a stretch.
This whole page write is cool, I can go on for ... 🙂
From what I've seen in only 2 days of hanging around here, I have to say that Toby and Franz are running a very nice operation. It feels like a real entity, a new breed of Open Source project using all the available resources at their disposal. The adjective that comes to my mind is clean.
All the best to Flarum, you've got my vote.
