Looking for 'stickys'

What will make you want to visit my blog on a regular basis and prevent your ADD from kicking in?  I'm trying to come up with ideas for people to 'stick' around and browse my blog, whether it be something interactive, entertaining, or even compelling- all within the scope of writing and fiction.  The idea of a forum of sorts came to mind but I don't want to moderate and I want to avoid drama.  Sudoku?  Crosswords?  Comics?  I can draw but not very well.  What has drawn you into other blogs?
