Latest gardening mistake

Yesterday, I cut and laid landscape fabric on the paths of my vegetable garden to create a weed barrier, tucking the edges under stones.  Then, I spread a layer of wood mulch on top of the fabric. Today, to my consternation, I read on various gardening blogs that the fabric isn't any good, as it prevents water and organic matter (including broken-down mulch) from reaching the soil. Shoot! My dirty little secret is: I put the stuff down around my raspberry bushes and newly planted shrubs.

Has anyone had any luck with this fabric?
