Quote from darkhorse:
Might I suggest the value of ET is 95 / 5. That is to say, 95% of the value comes from 5% of the posts. (Those who post the good stuff also get personal value from the clarification of ideas and the mental stimulation of open exchange.)
With that said, the "other" 95% is necessary to sustain ET as a community. Similar to Ken Grant's observation that 90% of a good trader's profits will probably come from 10% of his trades -- but he still needs the breakevens to get the home runs.
The problem with many threads is simply muddled thinking. Because the cost of creating a new thread or a new post is essentially zero, people routinely offer up the first thing that pops into their heads without thinking it through. (Or they will post a question that has already been answered a thousand times.)
But why get upset about that? It's the nature of the beast -- mediocrity dominates by definition, so just appreciate the excellence and shrug off the slop. (As usual I learned this one the hard way. When an outrageous display of ignorance comes around, I still have to fight the urge to respond, and still occasionally give in.)
As for the basic flaws in TA, the thread might as well be discussing the basic flaws in capitalism. Criticisms will be too narrow because the topic is too broad. What you wind up with is a 'blind men and the elephant' exercise: one is describing the trunk, another the ear, another the foot and so on.
