Just goes to show, if you want to know something, ask a (trusted, reality-based) blogger. This succinct explanation just in via email from Brian Leubitz of Calitics.com :

Here’s what I know. Edwards votes will count, but unless Edwards gets 15% in either the congressional district that you are in or the state as a whole, those votes won’t be counted for the delegate count. So, say in your congressional district Obama gets 47%, Clinton gets 45% and Edwards gets 8%, if you have a 3 delegate district (districts get between 3-6 delegates) 2 delegates will go to Obama, and one to Clinton, none to Edwards. Similarly at the state level, unless Edwards gets 15%, he won’t get any of the statewide delegate pool.

So, the votes will officially count, but they just won’t have a lot of meaning unless a lot of people vote for him.
