Well, I have to agree on most, except for #3.

I mean, first of all, commenting "nice post" or "amazing post" is pretty useless, even if you read the whole post thoroughly. Secondly, commenting is more than just for 'voting'. Sure, if you are saying how much you love a post, then maybe you should pair it up with an 'upvote' - however, comments can be more valuable than that (in case of encouragement/constructive criticism).

Furthermore, I am 'guilty' of not upvoting posts I comment on. Why? Because I had no idea about 'voting power' and I read too many posts and upvoted too many posts/comments in my first few days. I had to rest and barely not upvote anything for 2 days, but I am back over 95%, so I upvoted you because I afford to. But if my voting power is close to 85%, I will be very careful.

Not that my voting power really matters at this point, but it should soon and I need to keep it above 80% (as others suggested to me).

So, on that note, I would add another "Do Not Do" on the list: Upvoting/Commenting spree. Especially for minnows. Apart from the Voting Power, at peak hours your bandwidth will be low and you might be unable to post because you wasted it on meaningless comments. Make each comment count!
