Seriously, you won't get anything meaningful out of this, people will vote for the language they like and then bash the usual suspects (PHP, actionscript, C++,...). Also they will browse the first 20 entries or so and then get bored and skip to the end.
I'm sure the people who "dislike cobol" (7 people at the moment) have intimate knowledge of the language in production in order to cast such a vote.
It's just a popularity contest and a bad one at that.
Also: "Other - Dislike: 5 points". Enough said.
