Me too, I already exported my data from all platforms including HN and indexed them in a RAG database but I don't feel like using them much. They are past oriented and I need present oriented stuff. With LLMs I noticed I don't like when they use chat history search or memory functions, it makes them fall into a rut and become less creative.
I even got to a point where I made an "anti-memory system" - a MCP tool that just calls a model without context from the full conversation or past conversations, to get a fresh perspective. And I instruct the host model to reveal only partially the information we discussed, explaining that creativity is sparked when LLMs get to see not too much, not too little - like a sexy dress.
