We can't assume anyone who reads the contest entry thread will vote. . . We also can't assume everyone who reads the contest thread is a member of this site. . . VBulletin's "thread views," tallies the total number of views a thread has. . . including multiple views by the same user and guest views. . .
Guests always outnumber active members, and although there's almost 79,000 members on this site, it's always the same hundred or so members that log in. . . Of the seven people viewing the creative center right now, I'm the only member. . . Factoring that in, it's easy to imagine where those views came from. . .
So the reason there aren't a lot of physical votes is because the people who actually participated entered on whim and have no intentions of entering again. . . or personal reasons. . . and because guests can't vote. . .
Maybe someone could change that "Drawing Competition Anyone?" thread to a "Vote for your favorite." thread.
