Honestly, by and large I think communities like this are more damaging than you would think. Cloud kinda opened my eyes to this sometime back.
I mean everyone wants C&C because they want to get better, but getting better technically and getting better artistically are two MASSIVELY different things requiring a TOTALLY different set of environments. Generally speaking, getting better artistically is extraordinarily hard to do on a forum... PARTICULARLY when you consider the amount of times someone does something neat artisitcally and gets bashed up side the head and told they were "wrong" for not using the rule of thirds or (gasp!) angling your picture.
In other words, places like this actually can pretty effectively pound the creative elements out of you and make you think and produce just like everyone else in the throng.
There are those on this forum and places like it that think outside of the mere limitations of the technical requirements... cloud being one... craig being another really good example... there are others still... but they are few and far between, and for someone who isn't that experienced it's REALLY hard to tell whether these guys are the ones you should be listening to, or the 20 other people who said that unless you follow the golden mean that your picture sucks.
It's an irksome problem.
Be that as it may, if you do not know how to take a technically correct photo, how can you even possibly begin to get creative?
A ceramic artist needs to learn the technical aspects of throwing clay, using the different tools, firing the clay at the correct temperatures, using the correct glazes and firing them at the correct temperatures. Don't even get me started on other techniques such as Raku firing. The most artistic, creative person in the world, who has never worked with ceramics before, and just decides to pick it up, without learning the technical aspects of it will do nothing but create almost literal crap.
They could be doing something very creative (maybe adding a neat aspect of design, or something), but if the pot is cracked, and the glaze was over fired, or whatever, that creative aspect doesn't matter at all!
The biggest problem here is that most of the issues aren't creativity problems. They are technical problems. I've discussed this in the past, but I hate the way the so-called "Rules" of photography are taught. (I've mentioned my blog post linked in my sig about this.) It really does stifle creativity. I've seen shots that would have been absolutely stunning, if the photographer
hadn't used the RoT. But, in order to be creative, you need to know what the human brain likes to see, what it doesn't like to see, and when to throw both of those out, and do something different that might be something the human brain will like to see.
I know that when I give C&C, if I see the OP trying something out of the ordinary, I'll make it a point to comment on that, and that I like the way they are trying to step out of the box. But if they tilt the photo, but everything else is wrong (out of focus, centered, wrong DoF, etc) guess what, it makes no difference at all that they tried tilting the photo, and the tilting likely makes it look worse, whereas had they understood the technical aspects of photography, it might have made for an interesting photo.
