I think you guys are responding to the title, not the question. OP is wondering how to organize the history of chats.
What I've said does smell of the Super Smart(tm) and completely unhelpful Stack Overflow response, I will give you that.
Beyond that, the previous chats could practically be deleted for me. Its not like my prompts are such works of art that I couldn't recreate the thought if needed. Not to mention, Sonnet has made me not use chatGPT for about a month now so the blog is nicely divorced from the LLM flavor.
