In this case, both posts are good, but YM's post gives actual, useful numbers for things and details what happens when you go past them. Lamp's is about how to check the number of edicts, but not what a good number is, or what the consequences really are. That's the difference between a simply informative post (Lamp's), and an informative and useful post (YM's). On their own, they are both missing something; together, YM's is the better of the two for most people.
It has nothing to do with YM or Lamp specifically. But that doesn't mean their thanks count doesn't reflect their tendencies, either.
Also, I don't tend to thank YM because that's one more thanks I need in my quest to displace him as the #2 Thanks Haver. So if I thank YM's post you know it's a good one.
