Could you share more details about what changed your opinion? I don't know much about discourse, but I can say that for me, phpBB doesn't facilitate following and participating in conversations that are relevant to me. I find myself spending a lot of time navigating around. Specifically, sometimes I will skip conversations in a sub-forum because I don't care to read them. Then I will arrive at the front page, see a red icon on the left, and on the right it shows a topic that I wanted to follow. I will go to it only to find out that it doesn't have any more posts, the icon was red because I didn't read another topic in the same sub-forum. If Discourse were to provide a better user experience than this, I would be willing to try it.
