Other basically covers any fields you can't think of. Say a user wants to vote a particular way and the correct field isn't there, (s)he can vote in 'other' rather than not at all. It also shows you clearly if the issues you mention are indeed the ones that everyone is concerned about, rather than just being the best one they can see. It's pretty standard in any multiple choice thing like this where responses are rather limited.

In a largely unrelated note, could everyone (this means you) please sign this and pass it on to other users if you so wish, I would greatly appreciate it. Thanks in advance.
