Ah, but you misunderstand.
Subjectivity goes along with criticism, which is perfectly understandable - you will see many users disagreeing with my choice for this week's challenge and others accepting my decision. I'm actually grateful to be supported by the authors, who submitted the most creative and professional looking entries, which shows me that experienced photographers agree that assignments should not be accepted literally. As I've said, autumn foliage does not translate to "one thousand shots of tree leaves", but people should've used the autumn foliage as their creative canvas. And the (subjective and according to my taste) winners did.
What I don't agree with is technically incorrect opinions and bashing by disgruntled users whose photos weren't selected.
For example, @t3ran13 posted multiple times in the comments, calling me crazy and a drug addict. I've not called his entries bad or insult him in any way, but there it is - a disgruntled user, whose photos weren't selected. I should've downvoted his posts, because of the personal insults, but I haven't.
But when someone, like @knight-angel, expresses an opinion, which shows his blatant lack of any photography knowledge (is there a photographer, who can't distinguish motion blur from bokeh?), I will downvote his comment. And I will continue downvoting any comments, in this or other threads, made by users who have no photographic experience, but who, for some unknown reason, feel the urge to publish their technically flawed opinion. This adds to the confusion of many aspiring photographers, who are here to learn from the work and words of experienced photographers.
