Well I first joined deviantArt for keeping favorites, I hadn't intended to upload anything of my own.
One thing on deviantArt that have helped me artistically are tutorials and guides for drawing and so on.
Seeing what other people have done can also help, and inspire me to try things out and experiment myself.
So unlike what I first had in mind I've been inspired to try creating, and my interest for other peoples art have grown as well.
I don't really know what else to say except it's a great site for anyone who likes or makes some form of art
