While watching other deviants' galleries and favourites, those ads keep showing up, promising they'll go away if I subscribe. Well, I don't plan to do it yet, and I don't mind the ads. As a matter of fact, most of them are very appealing, so I caught myself collecting them. And when you follow the links, you can get pleasantly surprised as I was with deviantART Prints [link] - a wonderful new world of art, indeed.
