Another thing we all have to keep in mind, is that stolid routine goes both ways.
I have certainly seen my fair share of uninformed persons who refuse to listen to advice here. If we stroll through any of the general inquiry lounges we'll see this. Either I just bought this, or I am going to get this, or here is my current system. right away we tend to offer the stipends that fit everyone. Stock lightly, prepare first or do not get what you are thinking about. The first of which from nearly all newbies is the denial phase. This other guy did it and he's working out just fine. My fish will be just happy. No matter what you say, I am going to do this. Sure my levels spiked and some of my fish died, won't happen again next time.
Generally followed by a more aggressive standard. Who are you to say I can't? I'm not asking for the problem you have answered, I'm looking for validation, dummy. I recall one gentleman on here who routinely did 90% plus water changes. I gave my two cents on smaller amount of water more frequently and nearly got my neck removed. My response was a bit off topic, but you have to assume that will happen in the full scope of information gathering.
But what if I do this to the tank? Why don't I overstock with a bigger filter? I can sacrifice here and add his here. Bargaining with the experiences of others and general guidelines to procure desired end. I don't know about you guys/gals, but I see this at the LFS all the time. Well, I can keep it in this tank for life, but I'll have to do (generic routine) to make it happen.
The next step we hardly see here. If someone has migrated properly through the rest of the process, and come to the conclusion they have to wait out proper set up, or not do as they had wished, they lose focus of the hobby. Might call it depressed that the projections either can't be done as wished, or require a monumental amount of effort to be done. This step (stage) weeds out most of the casual keepers from the monster keepers.
The end result is what we see here. Once you have moved through this scheme, gathered all of the information possible and have a full understanding of what is to be considered correct, you near the standard of "pro". At that point you see the mistakes others are making and the incorrect assumptions they adhere to. I'm sure we've all had the long winded explanation of a particular problem we have faced. The person responding will give massive amounts of information that ties in some way back to our goals, followed with a justified opinion of how to proceed.
Hopefully the ironic quality of this trend isn't lost, I thought it was quite clever. (there goes my ego again)
Anywhere along the way we will offer advice to others not as far progressed as we are, but we tend to get less emotional about it farther we come. The general consensus we reach is that a decision will lead to sad consequences, as it typically does. All we can due as the purveyors of information is offer it as objectively as possible, and as humbly as possible. With any amount of luck, those moving through the steps will learn from them as they go, as we did when we did them.
