Quote - I agree with most, but not all, of the points raised above. 

Folder structure: it may make SENSE to use a nested folder structure. For example, I've made a couple of free V4 clothes recently. Their geometries go in :runtime:geometries:svdl:v4clothing:
In my opinion, that's a logical folder structure. I start it with my screen name, since I'm the only one using that screen name (at least on 'rosity), I can be fairly sure that the subfolders I place within the "svdl" geometries folder will not be overwritten by someone else's stuff. Rather important, I'd say.

In fact, in my very non-humble opinion, this is EXACTLY what content providers should be doing.  Your stuff (and I have a fair bit of it) is a relative joy to work with because it's logically organized and, if I want to move stuff around, easy to locate.
