Your current categorization "system" – Hallowe'en (?!), Fun, Futuristic, etc. – appeals to amateurs and is near useless to professional typesetters.
I want to be able to see if a font has small caps, is suitable for body copy in books or is better for headlines and display, etc. It would also be great to be able to view by date designed and other typographic fine-tuning options.
Adobe has been in the font business for many decades. I would think that you could offer far better tools to find your font offerings.
