This is a great question, really. I think understanding it and keeping it in mind and shooting away helps people understand what to do before and after the shot is taken.
In some sense, I follow that idea in the back of my head and try to make something memorable. An additional complication is seeing something there that a casual viewer who wasn't there might not because I have an emotional attachment to the place or understand a context that wasn't there.
I have TONS of "snaps" in these two blog posts. Are some snaps? Are some photographs? Does the context of presenting them as a collection turn snaps into photographs?
Pride parade in my city (and first outing wth the K-5):

Subsequent outing, got a bit better:

I shot looking for memorable scenes. Then I edited and threw away non-memorable ones. Simple as that. Not all turned out perfect (ie: front focus), but the scenes were memorable. In that sense, some very iconic photographs in history are very imperfect.
