Good one. We tried integrating Discourse (this platform) with our blog comments, but we felt there was too much of a threshold to become a member before you could comment.
In a way, that’s good, it forces people to sign up to the forum.
But from the first week we tried it, we saw that it greatly decreased the number of comments we were getting through the blog using Disqus. So we kept it as it currently stands with 2 different platforms.
