I have noticed that after the initial bit of enthusiasm, the posts completely died off and there were long periods of inactivity.
This is sad, but I suspect has to do with the fact that choosing and selecting 5 pieces of work is more effort than it takes to casually sit in front of a computer and bang out various kopitiam topics to pass the day.
Perhaps indeed it is a chicken and egg thing, but just personally anyway I feel the major obstacle is that people need to help comment to keep the thing going. If, (and as has happened), people take the effort to post their pictures and the comments do not arrive, eventually the flow of pictures will halt as well. Jas and myself are supposed to moderate the forum; we're moderators, not commentators. When we can we try to drop some comments in, but if no one else is chipping in, the situation is lost.
I'm trying to do a rethink to maybe stimulate more portfolios (and pictures in general) as well as maybe comments.
One idea is possibly a picture of the week, not based on quality, but just selected at random, although it should have some merit as well. Thereafter, people can comment on this "highlighted" picture. Potentially, to also have a vote then to nominate the best "comment of the week". Or possibly to get a portfolio highlighted each week, and then to have the same process. The emphasis being not the best picture(s) but the best response.
