The "HaHa!"

I just wrote a "haha" comment. I realize often how difficult the "haha" is to understand. Where exactly is the "haha" coming from? What is it oriented to? The reader of my comment doesn't know for sure. Am I laughing at them? Am I laughing at something I said? It could be a full on belly laugh or just a simple "teehee". I often laugh at the wordage I used in a sentence, but the reader could think I'm laughing at the entire comment I just made which could easily make me seem like a simpleton. oh well... Haha!
