Frankly, because this is a cool place to be in!... Secondly, had to find some place where I could share my designs (some of them real $hitty!). If I remember correctly, this site was introduced to me by a friend. Since then, I have hardly visited any other art site but again, never needed to do so! Now, I use DA as my creative diary and showcase. And thanks to all of you who liked my work. I don't know very much about the tools I work with (!!) but yeah, I am trying to improvise... hopefully, each of my design will be better than the last!
