And then came post modernism
To be fair, I think there's a lot to what you say about writing - but I think writing and photography should not be compared in this way. The 'conventions' (a much better word than 'rules') for story-telling are not the same as the conventions for other kinds of writing (e.g. poetry). I often think a photograph is quite akin to a poem, and much less akin to prose story-telling (though a photograph can of course contain narrative, as can a poem). With a photograph (and a poem) there is less to tie it down, it has the capacity to be more easily and quickly spoilt, (or rescued) and there is less to fall back on when it comes to putting into words quite what it is that is the particular formula for it's success.
If nothing else, the answer to what makes a successful photograph or poem is less 'wordy', and more heart-felt.

Po-mo schpo-mo!

Postmodernism depends on the existence of preexisting methods/conventions/rules/law/blah of writing. You can't have Pynchon without a lot of leg work before him, so it's not like he's working without rules. Au contraire, he goes against the flow of the river, so that the river is still there!
I disagree about your comparison between photo and poetry. People always think of poems as beautiful heartfelt meaninglessness, especially in the West since the late 19th-early 20th Century, but a large portion of western poetry is narrative to a large extent. The Illiad? Paradise Lost? Elegy written in a country churchyard? Beowulf? Granted, you can point to Donne's poetry as more symbolic, but it is nevertheless highly structured. Rhyme, versification, prosody, sound effects, all that we call poetics is what structures poetry. Shakespeare didn't write poetry like Jackson Pollock paints. Rimbaud was one of the first to tear down the edifice of classical poetics, but he also was a master of it at seventeenth. Yet he came with his own principles: vision, hallucination, impressions. All of which you could call "technique."
You might argue in return that eastern poetry is different, but here I must retreat into my ignorance, and point to the fact that the most ethereal form (for westerners), the Japanese Haiku, still has a codified number of syllables.
Back to Wigwam Jones's original comment, he rightly pointed out that there are elements to a photo. Those elements are contignent, the product of a practice, but they exist nevertheless. I'm not a Positivist-type of codifier, but I don't think we can work on intuition alone in working/appreciating a photo, or any work of art for that matter. I'm also sick of people discrediting all sort of structure/technique because they are historically contingent. By the same reasoning, every person is historically contingent, therefore worthy of elimination.
The final point I'd like to raise is the fact that creating a photo can be a matter of seconds, so that by chance one can subscribe to a very elaborate but beautiful composition. Or not. People who paint "realist" painting take pains to decide which line goes where, and by doing so they force a compositional structure. Photo is a rare art in that composition can be left to chance. Not so with literature, music, sculpture or painting.
Cartier-Bresson was saying that the rules of composition help us understand why a picture is good, but also that we don't need to engrave the golden square on our ground glass. A trained eye will perceive a harmonious balance faster than it can be explicitely identified. All successful "intuitionists" are probably more aware of form than they'd care to admit...
