+My technique involves a lot of nesting to stay organized and although I've thought about a tag-based system the advantage of folder nesting is its compatibility with different operating systems. +
My pony images folder could use some more organization, to be honest.
I find that different methods of organization are best when you have different numbers of files to keep track of. Folder nesting works good up to a point, but then it becomes more of a hassle to upkeep it than something like a tagged system. Right now, one of the issues keeping me from going right to a tagged system is that there doesn't seem to be an equivalent function to the galleries/pools function on the boorus. an ordered file collection for variant images or artist sets.
