Facebook chat friends bar order?

[pookie1231]

You know on the chat sidebar? Why are there random people above the alphabetical list of online friends? I don't go on Facebook much at all and although there are some people who I do interact with most on it, there are also some people who I've never spoken to before.

I get curious
Perhaps it would be helpful if I said I don't interact with some of the people on Facebook either, nor do I go on their pages or like their photos or statuses, or even look at them.

They just appear in random order.
