I've remember reading of a Talkyard as a replacement for Disqus. If this is the same one, have you pivoted in a different direction?
Yes it's still a replacement for Disqus etc, probably will always be (I'm using it a bit myself for blog comments :- ))
Development wise, most focus is on forum software / Q&A use cases.
Personally, I think a Disqus replacement is/was a good idea. I just would have preferred that the license were of a more permissive kind such as BSD or MIT.
