I’m also involved with that program, if anyone’s interested (in another thread at another time).
We’ll continue to improve this, but have you played around at all on advanced search? If I search for chair, low poly (< 100,000 polygons), in a catalog, sorted by popularity, I get a reasonable set of stand-in generic chairs.
Look at the bottom of those results, and see the collections that contain this model, and someone’s probably already created a collection of similar models.
Lastly, we really try not to get in the way of a user community. Each person on this list would curate a unique collection of models. If you’re reasonably saavy, you’ll find others in the community with similar tastes and interests that will speed you along your way.
