Johan,
I understand how you must feel. Removing a feature you strongly believed in and worked very hard for to implement (even though only on a test basis) must be really hard. However, apparantly the majority of the well-known contributors and participators voted against it. I'm pretty sure all of them really appreciate the fact that you've listened to their feedback and decided to remove it, even while you continued to believe in this feature. You could have ignored the comments, but you didn't. Therefor, a big 'thumbs up'.
Me, at first I liked the idea a lot, but I started wondering how many people would make use of this new feature?
OK, it's a bit easier writing a plain comment than sending an email to the photographer stating that a certain photo is excellent, but isn't it so that if somebody really likes a certain photo and wants to show his/her appreciation, he/she will still send an email to the photographer, without having to make it public? So, in fact the viewers of the site already dó show their appreciation, it just stays between them and the photographer.
It's nice to get feedback from viewers (both positive and negative) but getting those comments by email is just as good for me. On the other hand, something like 'Give your comment' could provoke more actual comments on photos than 'Send an email'.
I can also very well imagine some photographers were getting a bit afraid that comments (especially the first comments of a photo) could bias potential users/buyers of photos. Comments might influence one's opinion on the same photo. Nothing is as bad as a biased opinion.
Personally, I believe more in a combination of a rating system like the one Erwin showed (layout-wise) with the 'comments by email' function. Maybe something like this could eventually replace the system where the number of hits decides on the top photos. Imagine something like '5 Stars Of Today' or so.
Or, if the photographers could choose between making the comments on their photos public or not, this could mean a new start for this project.
Greets,
Ivan
