We are trying to build the 'Yelp of Personal Finances' at SuperMoney. It's basically a community driven reviews site in the personal finance niche.
One of the things we are doing differently is storing a lot of weighted product attribute data and combining that with user sentiment reviews to algorithmically score various products/services.
The end result is a numerical 0-100 ranking of companies.
I was hoping to get the community's thoughts on using a numerical rating system as opposed to a conventional star rating system. I realize it breaks convention but, personally, I feel like the star rating system is generic and imprecise. But my concern is, whether I'm sacrificing usability for what I perceive as a better system.
We are also showing a purely user rating via the star system. I'm not sure if this is confusing or not. I should probably distinguish the two better.
Would love to hear your feedback on the above and anything else on the site.
