A couple of points...
It's a skinner's vanity that will blame a low rating on a 'drive-by' and not an experienced and valid opinion.
Example....my most 'difficult' Litestep theme dropped in its rating a few points...so I looked out of curiosity.....it was a 5 from Frogboy, someone with a whole SWAG of experience in skinning, so, though there was no 'comment', BUT the overall rating dropped a few points it actually was a fair and equitable assessment from someone whose opinion deserves appreciation and was NOT a drive-by at all.
People shouldn't be fazed by changes in their ratings....it's a simple product of time and exposure...but if there's an accross-the-board 'drop' in their gallery it's a simple process to email an admin to check that it's not something nefarious.
I bet I know more about subjective opinion than most....as an Architect I have to deal with Planners and Heritage Architects who arm themselves with 'guidelines' to mask their pure unadulterated petty subjectivity that is readily exposed by clear examples of hypocrisy...[they did it that way but I can't?].....currently a sore point with me that will likely see me walking away from 30 years of this bullshit.
However...
The 'I don't like it' "I hate it', etc of the mouse-overs is NOT subjective in itself.....only their application may be.
If I were to choose 'I hate it'...it will NOT be for the reason I may not like the person....or it's pink and I hate pink....it'll be a considered opinion of all criteria that can affect the work as a whole...like how simplistic it is...or how 'common' or 'derived', how 'buggy'...how 'incomplete', and, obviously how 'ugly'.
The last one is 'subjective'...the others are merely 'comparative' or 'relative.
If 'simplistic' were the only attributable failing in determining a skin's 'worth', for example...then you'd expect to see Beatnik skins all at '1'...and WB skins all at '10'....but that is not how it works....and anyone who can be seen to be that stupid doesn't deserve to be rating, let alone drawing breath...
Again....this $10 per 'rating thread' getting me to the South of France and drinking copious reds is still looking good...
