I have several tools that do this sort of thing, including a 'bot that can be invoked automatically on mastodon. I don't do that on Twitter because popular discussions get seriously out of hand ... there was one that I stopped tracing after if got to 3500 tweets. I have some heuristics in mind to help control that, but it's all still very experimental.
I also have a pig-ugly, pre-alpha, bug-ridden discussion system that works directly on a DiGraph, but when it was submitted to HN sometime ago reactions were ... (significant pause) ... mixed.
