> If no one agreed with them then theirs would be the only flag and there would be no effect. If several people agreed then there would be several flags, and that's what appears to happen.

It would be good if users were given not only flag, but also unflag possibility. As it is right now, it takes only a few users to flag an article to disappear, although there might be hundreds users that would be opposed to that that can affect the flagging process because there is no unflag option.

There is an unflag option, it's voting that can't be undone, and you can't downvote a submission.

There is unflag option where you can unflag your own flag, but it doesn't counter other peoples flags, IIRC. I'm not sure about that now, since flag right has been removed from my account some time ago, and I don't see neither flag nor unflag links anymore.

Why should you ever be able to undo someone else's flag?

[markokocic]

Why would someone else's flag affect my front page?

[ColinWright]

I really, really don't understand your question.

Consider your front page. It's the same as everyone else's front page. The ranking of the items is a function of how old each item is, how many points it has, how many flags it's got, whether it's trip a filter, etc.

Now I flag an item. That penalizes the item and causes its computed value to fall. This in turn may cause its position in the rankings to fall, and thus will affect the front page.

But the front page is your front page, and hence my flagging an item can affect "your" front page.

How can you think it would be otherwise?
