I'd add to Richard's mea culpa, in reply #67, re editorial style of presentation of haiku having perhaps to do with to its future as a genre, that this can be seen as a (creative) kind of criticism -- with a role to play in haiku criticism. Whether, for instance, a normative 3-line haiku appears among similar haiku or juxtaposed with a long-lined short poem in stanzas with a title may affect the kind of attention you pay to it. The change of pace will give you pause; the formal differences might make you consider the choice of form -- its appropriateness or limitation -- more carefully than you would otherwise; at the same time you might read with a keener eye for what the two poems have in common, how they relate thematically and play off or deepen one another. On a larger scale, this may touch on a new sense of poetic community (or commonality), which may in turn shift the critical mindset or frame of reference.
