I've read it should be okay for ~3 years unless it smells funny or you can tell its separating/crystallizing but I'd use it with caution.

I haven't either and apparently mine is still okay, it expired in 2006 and I'm not burning when I use it.

I wonder what expiration dates are for, then.

Expiration dates just mean the company had evidence/test results that at that age the product is still effective. Usually, companies only test as long as required instead of spending the money to test a product's actual life span.

Ah, well that makes sense. Very interesting. I wonder if there's any way to speed up the process.

Maybe, expiration dates just mean how long the company tested it and can prove it is effective. If it doesn't have a date it still should be good ~3 years but from what I read as long as it doesn't look or smell funny it may still be okay just less

effective. Use more or more often or toss it.
