I think I will put that rule into place. I also only voted for my own entry when I saw that everyone else had done the same.Personally I never vote for my own entry. In fact when I have an entry in a contest I usually don't vote, unless there's another entry which is so very good that it deserves my vote.
We could have a rule which says: 'do not vote for your own entry' but there's a danger then that we will get very few votes overall. This particular contest had a lot more entries than previous ones, so I suggest we wait to see how the next one goes before introducing a new rule. (That's just my opinion - if the majority opinion differs, let's go with it.)
Edit: we could have this as a tie-breaker, perhaps? If there's a tie, 'own-votes' are subtracted?
@Meshakhad - I like the new contest - should produce some interesting work!
I dont think it is a rule. Just something some of us debated. In past threads nearly everyone voted for their own entries, myself included, and it made it difficult to find a winner.
