This site has a newish page called, imaginatively, New Links for You!
It includes several contests that are active right now for work that pushes past boundaries and explores new potentials for methods of creating something unusually unique.
There are other elements as well presented with a growing list of links to news, books, magazines, websites, aps and more. Many notices include more about them than the straight-up links on the regular, huge, page About Experimental Writing.
