I've known about deviantART for awhile now, but I haven't actually uploaded anything, nor do I plan to in the forseeable future. If, however, I get a flash of artistic inspiration and decide to draw concept art for one of the many story ideas I have, or anything else, I know just where to put it. Likewise, my YouTube channel [link]
currently has no uploads, but I have ideas for a regular videoblog.
In case you want to see sites where I do have stuff posted, then check out these links:
