All right, I'm going to keep this short and sweet for you.  I've been composting for a long time, and in general I'm not really into the whole scientific side of it.  I'd rather have a general idea and help spread that to the masses...too many details leads to analysis paralysis.

The composting process can be kept to a few simple rules:  3:1 carbon to nitrogen, no meat/dairy/oils, have fun.  Recently, I've been receiving a lot of questions about whether or not citrus fruit belongs in your compost pile...yes!

I'm not sure how this urban legend really came to fruition, but it's simply not something to worry about.  It seems the common belief is that it takes longer to decompose, which is technically true, but barely.  A chemical by the name of limonene needs to be chewed by particular bacteria, but as soon as that happens it's like anything else.  In fact, citrus fruits will heat up your pile quite nicely.

A week ago, I received a gift in the form of a 5 gallon bucket of waste from a juicer.  As you can guess, my pile nearly doubled its temperature as a result of this fruity gift.  What it comes down to is that if you make any reasonable attempt at composting, you're not going to have any issues with this.

My hunch is that the myth evolved from vermicomposting first, as citrus peels are not a worm's favorite snack.  Nonetheless, even with worms you can feed them a limited amount of it.  Moral of the story, when it comes to citrus fruit waste, let it rip!
