I agree.
I also think the whole “positive” approach is quite strange in general.
The kind of “Pleasantville” communication forced upon users is unreasonable and degrades the value of all communication on the site.
There is no good without reference to bad. No black without white.
I think that users on all sites should be given the opportunity to “boo” or at least disagree.
For example there is a user cluttering up Iceland with pictures and cheering them to first place with a number of alternative profiles overriding all other users.
Though I have reported him neither he nor any of his alternative profiles have been taken out.
If we could just “boo” his pictures then perhaps the situation would be a bit fairer to other users..
