In this app, the process runs entirely in the browser and has no LLM calls at all, so we don't have the ability to rewrite the conversation (other than performing regexes or other crude operations on the text of a comment, which is how links are turned into "See the link I posted in the thread").

I also think it's incredibly difficult (even with an LLM) to render properly a multi-turn multi-user conversation without sticking to the actual hierarchy of the thread. We would probably run into the "summarize the thread and lose nuance" problem again.
