No, not the flaming topic from a post being replied to XXX number of times but getting hot (or something better) from XXX number of page views.

For instance,
It turns hot pink, or whatever, if the topic is viewed 500 times no matter how many replies it gets.

I see that this would be good in many different forums, such as forums that post a large number of jokes where it is not important how many people reply but how many people read it.

Or like News forums where not many people reply but alot view it.
Maybe a heavy traffic icon or something.
It would signify which threads on getting the most attention, without really worrying about how many replies.

Do you see what I mean.
It is a fairly new idea as most boards do not have the viewed category on it.
And since vbulletin does it would be a cool little extra.
But a name for this occurance and a icon would need to be made for it.
