Postbit Hack

[Bilderback]

I just thought of a really cool and useful postbit template hack but I dont have the time to complete it.
Its actually fairly simple-
All of you must have seen forums with huge amounts of information and images in the postbit
which tends to make the actual posts and replies look very small(alot of empty space).
If you were to add a post length requirement, lets say, 25 to 50 characters as a conditional to the full postbit, otherwise, it would only display the user name.
This would shorten the forum with the minimized postbit for those who have short replies
and also gives members an incentive on posting lengthy replies.
In summary:
Condition= If your post is too short, your full postbit will not display(ie, only your name and rank?).
If the length of your post meets the minimum requirement, your full postbit will then display.
If anyone would like to develop this idea into a hack, I would be very grateful.
