The Chat Laugh Hierarchy

Chatting over the internet is a mainstream form of communication now.
While I miss phone calls and face-to-face visits, I've accepted reality I've embraced chatting.
Note: A video chat is preferred, but sometimes that's not possible (dang you, work).

Now I just have one question:
Does anyone know the hierarchy of the various chat laughs?

I mean, some are pretty clear. We can figure that

• ha < haha < hahaha (multiplication rule)
• lol < LOL (bigger-is-better rule)
• haha < bwahaha (exclamatory addition rule)
• and LMAO < ROFLMAO (loss of body control rule).

Those are obvious.

Others aren't so easy to determine. For example, I figure that

• haha < harhar
• Why? Because "harhar" first reminds me of an old man or a pirate laughing in his armchair. Hmm, but I suppose it could just be someone with asthma, and thus wouldn't be as hearty a laugh as "haha". I'm torn on this one, but I think I'll go with my first instinct.

Cap'n Happy agrees that haha < harhar

• haha < lol
• Why? Because I figure that "haha" has been around for a long time, and "lol" just popped into existence with the dawning of internet chat. So it stands to reason that newer would be better/bigger than older, right? Saying that haha < lol raises other issues, like what happens when other rules (such the multiplication or bigger-is-better rules mentioned above) are included?
• Would hahaha still be < lol?
• Is lol < bwahaha?

Nelson might dispute my haha < lol ranking

So what do you think? Are there any others I should be aware of for regular chat laughing, and that need to be included in this hierarchy of chat laughs?
