Seriously I don't want to get into an argument with anyone regarding their choice of website - the internet is free and full of information, read what you want to read, believe whatever suit your need.

There are very good sites such as B&H offering real world experiences about any lens by real users - take trouble to read their reviews, some are non-technical some are in-depth and among them we can make up our mind.  For real technical reviews navigate to bythom or photozone, their lens reviews are unbiased and thorough.  As for me I treat KR opinions similar to my "next door neighbour's" purely non-technical and superficial, easy read and a good source of entertainment.
