In my books I might hold the mirror to my own face. If others would like to borrow the mirror, they're welcome. The books aren't there to accuse others - merely to raise issues and keep the debates alive.
I don't see myself as experimenting in any conscious way, it's perhaps that certain books require different densities of language.
The true experimenters are there but no-one hears about them - the critical/review system tends to concentrate on the handful of 'major' writers and their promising successors; bookshops tend not to sell them; publishers don't promote them. It's the same fate as has befallen poetry.
