I find very little on that site that actually imparts anything to my game. Take that statement as you will.
I'm not much of a rules lawyer. My major concerns IMC are: "Is it fun" and "Does it make sense to us".
But as I on occassion run into rules lawyers, in the form of power gamers, I find it handy to have at least an inkling of what tricks they are trying to pull, and therefore frequent this forum. I will always regard supplementary information as just that. Not more or less valid than any other moderately informed opinion. It all has to be filtered.
It takes time and effort to stay informed. With two kids, an abode, and a few other things going on, like trying to put food on a table, I have to restrict myself to certain sites that have a high return value to me and my campaign. I find ENWorld provides a greater value for me than the WotC site. Thereof my original statement, which I stand by. YMMV.
