Overdoing it is #1 reason for burn out!  That's why I'm not.  My comments are like money (IE: Time,too)  and I spend 'em where they might do good.  You just have to use a little reason and judgement.  Ask yourself the following questions:

1. Do I have experience with the software they're using? 
2. Did I notice something out-of-whack that no one else mentioned?
3. Have I done the very same bad thing I'm looking at right now?
   4)Did I just remember a thread mentioning fixes for this problems?

Yes to any of the above--comment away!
There are a couple of other reasons in my book,too.

A) Is this the most realistic looking render you've ever seen?
B) Did this affect you like a punch in the gut?
C) Did this piece have an element in it you always wanted to do and never did successfully?
D) Did this make your eyes bug out, or drop your jaw?

Yes to any above--blather away!

I've only commented on less than maybe 30% or less of all the ebots, I've ever recieved.  They're simple questions going from my criteria, not yours.  I'm not burned out because I set up my own rules and have tried to live by them.  Meh on complex rules! SImple rules, rule my day and comments. :lol:
