Certainly, people may only choose products that are 0.9+, but the point is that the *range* of good products in 0.5 to 1.0 rather than 4.5 to 5.0. Anything rated above 0.5 is something that is generally "good" and people may be more comfortable buying things in a lower range.

A big factor in how this plays out is how you *show* the rating to the end user. Showing stars or numbers may not be optimal. We need to be creative in how we convey this information so the sentiment is not lost as well. I don't have all the answers but we will get there with experimentation.
