I think having the yes no comment vote works better than just the vote on post mainly due to all the vote trails and such. That being said I do vote yes, and have/will vote the post.

Once your post has been picked up by tracking (an archon user with > 0.001 GP upvotes it) a bot will automatically place a yes and no comment for users to vote on.

this will really come in handy when it is fully up and running.
