Sure, different strokes and all, but there are also lots of people (far more, I'd say) that prefer to be "rewarded" for all of their "work". I think that's what many in here are doing, expressing their frustration that they put way more into it than others and know far more but it isn't nearly as much of an advantage as it used to be.
WDIS hasn't changed though, it's always been a bit of a crapshoot. What has changed is the effort required to gather all of the information/opinions/projections/historical data- everything is at your fingertips now, much of it is even being pushed out to you.
Again, not saying it's impossible to gain an advantage, it's just the advantage is much smaller than it used to be IMO. Like I said, some/many prefer it that way, but it is what it is. Those who put in the extra work previously had all kinds of information that others did not, now that big edge is essentially gone and you're only left with what to do with it.
