In general we are not to crazy about micros, after all standing in the middle of a wal-mart parking lot rubbing up and down a lamp post is not cool! However in bad climate, or limited time they do fill the void.
But is also getting to the point where someone will post a cache as "it's so small and so well hidden that no one will ever find it" and then not hide anything. Great thing about Geocaching is you always have options.
