Whether to capitalise or not to capitalize the start of lines

[milo]

I have been reading more and more critiques (or comments if you prefer) addressing the capitalization of first words in lines of poetry.  The occurrence of this type of critique has been growing both in popularity as well as in vehemence on this very board.  It is not only this board that suffers this:

I have read quite a bit of poetry both of the modern variety and of the more dated variety and I have seen no consensus on the issue.  Poem published today, both in print and on line feature both standards - sometimes within the same publication.

Do people find this type of critique valuable?
Do people believe there is a consensus "right" way or "wrong" way?

Just some thoughts for discussion on an issue that has been nagging me for quite some time.
