Personally, my experience matches Tuna's. Seekers of Perl Wisdom is, imho, the best place to post--especially if you're not sure about your approach, algorithms, or understanding.
That said, *some* monks are able to express certain challenges as "golfs" and tend to post these as Meditations. I suppose the difference is purely arbitrary. However, I've noticed that SOPW is a fairly safe place to post if you're unsure.
To my mind, snippets should be clever--short--bits that solve a given problem regardless of context. Perhaps not enough to be Cool, but more than a simple Q&A. Polished code, otoh, should be Craft or Cool. YMMV.
