Just so you know where I'm coming from. I and my circle of friends are anxiety ridden about every decision we make or have made. So speaking for those people:
A testimonial/feedback section maybe nice. Personally, with all the riff-raft, I understand why you wouldn't want it. But when shopping online, I make my decision based on reviews.
Also, categorizing(general, love, finance, etc)your spreads instead of having it be all in one list. There will be plenty of people still confused of which spread to pick even if you do...it though it makes it that much easier for to make up their mind.
