To be perfectly honest, I absolutely agree with #3. A bit of formatting
- Makes the post more readable
- proves that the user put a bit of effort into it
- prevents the "Wall of Text crits you" effect
- stands out
- allows me to spot important points more easily
- puts some structure into the posting
And #6 is also a no-brainer. Not because of the reputation but because that gives clickable names when migrating the question.
Point #1 is well discussed, just search for the fastest gun in the west problem. And Point #5 benefits the person who asks the question, because more visibility = more chance for an answer without having to post a bounty.
So only Point #2 is purely evil and should be somehow monitored and actively counterattacked, but I think that's what Jeff & Co. have been doing since almost Day 1.
But overall, I agree with these points, because nicely formatted answers from people with accounts who bump the question once in a while to give it more exposure are a Win for the site.
To further prove my point, here is a picture of a bunny with a pancake on its head:
