Theoretically, I post a picture every day of something I created. Sketches, full color pictures, crafts, food, photos. I also rant about things that I have strong feelings about.
I also have a tumblr about being trans, and general trans stuff:

My cat has a tumblr in which she complains about people she thinks are assholes, and also posts pictures of herself because she's a sexy beast:
