Facebook is just social networking web site. People can get bored and use some other web site. Amazon is only a shopping web site and a hosting company. There are popular companis like Amazon, such as AliBaba and DigitalOcean. There is nothing special about Amazon. Google is a search engine, smart phone OS, mail, maps, video service, web browser. Looks like Google has way more chanse than Facebook and Amazon. |

But there is a huge amount of value tied up in those reviews. I'd argue that it creates such a network effect that starting up a competitor would be really hard. Possible but Amazon would have to stumble.
