Hi Flatland,
The projects in the poll most certainly have differing ranges of quality and completeness. The idea of the Most Outstanding category is to determine which have been brought to the highest levels of polish and professionalism-- if a project's not complete, then don't vote for it
If there are serious questions as to whether the winning project is complete, the admins can make the final call to disqualify.
Hope that helps,
Kaitlin
