I've just added a lot to my already massive blogroll (down the side there) - but there is so much amazing writing/writing about writing/post-writing (I'm not sure what else to call it - vispo and the like) out there. Check out, especially, The New Post-literate, mIEKAL aND's work here, Reed Altemus and Ross Priddle. (New Links came from here - there are more).
Two other online poets who I have been following for some time, and whose work is amazing, are John M Bennett and Lanny Quarles (Lanny has another blog here).
I also just ordered a copy of the Late Great Leigh Davis' Willy's Gazette (The Jack Books reprint) off Abebooks - The first copy I've ever seen for sale (though maybe there are copies floating around up north). I'm eagerly awaiting it's arrival.
