I think it is also important to allow someone (admin or author) to split apart a complex user voice idea into its component parts. Case in point: I recently encountered a uservoice idea for an iPhone app + data in a cloud for Personal Brain. I don't have an iPhone but am interested in Personal Brain data in a cloud and cloud computing allowing use from a host of remote devices. I believe cloud computing is a separate and bigger issue than iPhone app. I did start a new user voice idea but have garnered no other votes than my own. I am left to compete against this cloud concept wrapping in with very very popular iPhone app.
