Thanks to all for the replies and comments! This clears up most of my questions.

I realize there is a potential for abuse in any ratings systems, wether it is biased by the "buddy system" or not, but it is still nice to get feedback on your submissions and some competion (today's top list or top100, whatever)  provides goals and the gives the artist a sense of accomplishment, or recognition, when reached.

Art should be pursued for it's own sake, as opinions will always vary and should not influence the artist from his/her visions. But a lot of what is posted here requires as much technical skill as artistic, and the feedback and tips on the techincal side can be invaluable to the nuby.

Would I like my art to be rated in the top 100, sure, but only if it deserves it and not just as a result of a popularity contest.

Thanks again.
