> 5.) edit: Here's another: Karma is directly proportional to how early you post in the thread (by virtue of time being linear and people only visiting a thread a certain number of times).

Though not perfect, an incomplete solution to the timing issue you mentioned is already in place. A new comment can show up at the top for a while, but the karma and age of the account may be weighting factors to prevent trolls from getting the top spot. The position of the comment degrades over time, and of course, how fast it degrades depends on points it receives. This doesn't work perfectly, but it's better than nothing.
