I've got a drawing app on my phone, Autodesk SketchBook, which recently added DeviantArt integration, the main interesting feature of which is challenge prompts. These are great, because more often than not when I open the app it's because I want to draw, not because I have something to draw, and it's super frustrating to draw the same couple scribbles over and over again.
I'll probably start to upload some other stuff there too, it'd be nice to have a convenient place to point to for a portfolio. I don't think I'm going to try too hard to maintain it, though, because I've got enough online identity maintenance to handle right now that I don't want to have to learn how to interact with a whole new website on a serious level.
Let me know if there's any art you know I've done that you think should be online.
