I love having a porch. It's the overlapping of indoors and outdoors, public and private, personal and community. Libby recently rearranged ours and feels even more living room like than our actual living room.
Gibbie's favorite thing to do on the porch is make a nest out of pillows and blankets (but mostly pillows). He'll spend a long time contentedly being a little bird going in and out of his nest.
