I see two threads with multiple exclamation points in today's list of hot threads.

A general rule of thumb is that the more exclamation points used, the less important the message. This is because the user feels the need to compensate for the triviality of the message by increasing the number of ! points.

So, with the exception of this thread, I would advise skipping threads with lots of exclamation points in the title. (Except for this one!!!!)
