Except for the bit where I got mixed up, I'm in no way an accessibilty person, I do usability and search stuff, in the above where I say "bad for usability and accessibility" I meant "usability and search optimisation", I don't know what it's like for accessibility and given my previous sentence was about the potential clash, that makes no sense at all.

And thank you. The flu is going away, now I merely need to deal witha broken tooth :-(
