Setting aside (for the moment) the base idea and assuming I agreed with the idea of categorization (I don’t), not having subcategories - and sub-subcategories ad nauseum would be insane! Consider for a moment the range of models found in the 3DWarehouse - here’s what I found with just a few keywords (with # of model hits):
- Bong - 184
- Screw - 32,976
- Bollard - 754
- Bollard Light - 156
- Lego - 4,311
- Painting - 18,780
- Grass - 5,266
- Button - 3,660
The universe of things that can be categorized with one or two words is immense! How would this be presented? A really long scrolling list? Alphabetically? A search page just to find a category?
Now on to why I think categories are a bad idea:
Consider the universe of “things manufacturers make”. This already has a categorization scheme of 2, 4, 6, and 8 digit numbers called the UNSPSC®. It is formed XXYYZZAA where increasing length is increasing specificity. So even WITH subcategorization, you’ll have up to 100 choices at each level (10 million if you don’t subcategorize!).
And this ignores things that manufacturers don’t make! Add all wild animals, all insects that anyone has modeled. Spaceships.
I’m sorry. When I search the 3D Warehouse, I almost always have something in mind which suggests a keyword or two or three. If I don’t find exactly what I want, I look at something close - and what keywords are associated with it to suggest another keyword search. I can’t recall not finding what I need in 3 searches or less!! And it’s a lot less effort than paging through 3 or 4 levels of subcategorization, each level with (potentially) 100+ choices.
I can sympathize with the desire to discover what might be in the warehouse that you haven’t considered ever looking for. It’s neat to explore! To that end, I could easily support browseable pages of:
- A random selection of new uploads
- A random selection of models with fewer than 3 keywords
- A random selection of popular downloads
with each page having 10-20 models.
