Related to my previous post, I found Lucas Gonze's entry on the lowercase semantic web via Marc's voice. I'll definitively be following what Lucas' writes.
Lucas' expresses some of the issues I've had over micro formats in a much more succint (and perhaps less brutal) way:
I don't mean to overcommit to this argument. The problem I'm having is emotional, I think. lowercase semantic web feels like yet another religion, which I don't want. I see lots of value in being strict about HTML semantics, however I don't yet see why I'd want HTML semantics everywhere.
