Amazon is a powerhouse. Therefore, it is no surprise that it is a popular go-to business review site for e-commerce products. If you don't use Amazon, you probably know someone that has used Amazon (or uses Amazon faithfully). In fact, Amazon has been training consumers to use their review system for a long time now. Therefore, we should probably thank them for helping train a mass of consumers to start leaving them and making it as part of an online consumer etiquette, if you will.

Facebook is a social networking platform where users can create profiles, upload photos and videos, send messages and connect with friends, family and follow their favorite businesses and brands.
