Man, I luv's me a good internet fight that I'm not involved in...
I wore a hole in my cord at a double fisherman's knot. Ok, was on my Prusik cord on my harness, but, still. Left that rig as part of a rappel anchor. I still miss it. My two biners more, though.
Haven't used a double fisherman's to tie ropes together for some time. Still see folks do it, though. I much prefer a flemish bend and will leave a loop on the down side if I might need a clip in point. Unless I'm rappelling free air and then using two tied in ropes to belay with (a sketchy practise for TRin' really long routes), I use an EDK almost exclusively.
As far as using daisy chains to anchor in with, I don't consider one any more.

I do from time to time consider a Metolius loopy chain anchor thingy (I think Sterling makes one too). Pretty bomber and no loops to bust. Also, bit more "give" than dyneema/spectra. Most often I just anchor in with a simple sewn sling or two.
Anyone use a Purcell Prusik with sewn webbing? The more I play with that style of anchor, the more I like it.
