You make a fair point, Nightmare, so let me just address it by saying that there are a number of ways to be competitive. Most of those ways have attracted so many competitors (gaming sites are a dime a dozen, you might say, and already there are plenty of review factories that post tons of user reviews without any sort of personal touch) that we're left with what was always one of the best options: make sure that our writers feel that their work is valued.
My desire to leave old content on the site goes hand in hand with that. Even though they're not around right now, I believe that the people who wrote reviews such as this one deserve to know that there's a record of their effort on this site and that they don't have to worry about us working so hard to rush forward that we forget where we came from and forget the people who made it possible for us to get here.
Honestly, I don't see it as a huge deal anyway because the overwhelming majority of reviews posted on the site were and are excellent. The odds against someone coming across this one review and thinking poorly of the site because of it would have to be astronomical by this point.

"What if everything you see is more than what you see--the person next to you is a warrior and the space that appears empty is a secret door to another world? What if something appears that shouldn't? You either dismiss it, or you accept that there is much more to the world than you think. Perhaps it really is a doorway, and if you choose to go inside, you'll find many unexpected things." - Shigeru Miyamoto on secret doors to another world
