Keeping Your Poinsettia Year-Round

Have you tried to keep your poinsettias year-round?  I haven't yet but have kept two that I intend to keep for next Christmas.  I found a good instuctive video with details on the care and fertilization regime required to keep a poinsettia after the season.  Don't mind the voice on the video, which sounds somewhat automated and computerized.  The instruction is excellent!
