So this is something I'm sure has crossed our mind once in a while. Now when it comes down to it I feel both sites are a great place for art. Here's my point of view on it.
Newgrounds is a site based off quality and discovering established artists.
deviantArt is a place to share your art with other artists, and discovering the artist within.
Newground pros:
-The strict judgement system makes sure that mostly quality pieces get on the site.
-Its quite respectable to certain people be affiliated with ng.
-Sponsorship for artists for Tom, if good enough.
-If featured you gain some good exposure
-Honest criticism given by users.
-One of the best sites for flash games.
-Active admins
Newgournds cons
-The site is extremely inconvenient for checking comments, reviews, really any form of feedback.(possibly fixed in redesign)
-If you don't some kind of feature. The submission is usually barely seen, no real way to advertise yourself without being dependent on others.
-The only way ng enforces rules is usually just deleting, submissions/accounts, which can be extremely harsh for some.
-Voting system easily rigged.
-If your not an established artist, you have no business submitting.
-Asking anyone but Tom/staff for money usually gets you lased by users.
-Earlier signup dates somehow make you better/more intelligent, in forums.
Newgrounds user stereotype is, that everyone is an intimidating dick that's out to troll or attack users for the way they live their lives or express themselves through art. Although there is a solid group of people like this, and some of them are actually praised for this in some cases. A majority of ng is not like this.
deviantArt pros
-Site is very active, with submissions coming in by the second.
-The active community is a few million people
-Its convenient for checking notifications.
-You get updates for your favorite artists instantly.
-You can customize the kind of content your mostly exposed to with the watch function. Making it much easier to share your art independently.
-Groups are a good way to gain exposure.
-Its acceptable to ask users for money for your art.
-Users tent to be loyal to the site because they learned art from the users
-There are some well known artists/animators from tv shows that are active
deviantArt cons
-Critique is usually a touchy subject, some users will attack you if they disagree, even if its not their business to but in.
-There can be quite a bit of crap flowing in the "recent submissions" area.
-The staff is very hard to contact and inconvenient to talk to.
-Its easy to get well known, but sometimes for the wrong reason.
-Negative comments usually come with a price.
-White knighting happens quite a bit
deviantArt stereotype is that everyone is an annoying weeaboo, which its very accepted there. I can say a majority of the users are not. Although there is a strong cult of them. There isn't a lot compared to the entire site.
idk this is what what I observed from being on both sites over the years. What do you guys think?
