That is partly true, but i do have these points to bear in mind:
1. Product information has to remain similar otherwise you will run into all sorts of difficulties when selling a product that is described incorrectly. Therefore site content will have to be duplicated for this reason.
i.e. I would not want to change the directions to a parking site for the sake of seeming different enough to be listed in a directory, they'd end up in the wrong direction...
2. I appreciate the effort that editors go through when reviewing a site, but i would have also thought that site presentation, usability and consumer friendliness would have been a HUGE factor in determining whether a site is for 'human consumption' instead of one that has been 'composed' and is a mess of words merely to get number 1 in search engines. Surely that is why we have this great directory?
3. Demographically a huge amount of people use the internet for shopping around. Surely a site that can vastly aid the user in doing this, is justifiable cause enough to list a site that:
(a) offers a true and fair comparison service
(b) is presented for 'human consumption'
(c) is friendly and usable, especially when it comes to visual impairment and disabilities.
Therefore you are right in saying that you don't want to list sites that are almost carbon copies, duplicate site after duplicate site etc (which there are a huge amount of), but i believe that your rules should also allow for sites that satisfy the criteria above. It would be a great injustice to take away services that are easily digestable and benefit for the internet user.
I can but rest my case, and continue creating and expanding on a site that i am proud of, and that will continue to follow these ethics.
Thank you for your time.
