Actually, I do not want to be a slave of other's people who have already commented my work. I try to be gentle, but sometimes, I just can not fin a decent image which would justify a positive comment.
So far, what I have seen is that the trend in a lot of photoblogs is to "love" HDR pictures displaying such dramatic colors contrasts...For me, this is no longer photography, this is more related to paintings. I can not comment on that.
When I leave a comment, it's really because I love the image I've been looking at, not because I do expect a return comment to get me traffic increased.
As a result, even if I ranked amongst top 10 finalists in 2007 best new photoblog awards, my traffic is today very low. But I do not matter that much. When I have one pure emotional comment, it's worth 100 "nice job" or "good site"...
