Twitter has become quite the hotbed of chatter about functional programming over the past few months, as a substantial number of pretty well known FP people have either been present all along or have signed up recently and started following each other.

Here is a list of people I know about who tweet about FP on a semi-regular basis, along with what I think are their main interests. If you want to see the list extended or modified, let me know.
