Prime started as a two-day shipping membership for devoted Amazon shoppers, and it didn’t add any additional benefits until 2011. However, since then, Prime has grown into a subscription service with more than 100 million paid users worldwide, while the service itself has evolved to include additional perks over the years, including a Prime credit card now with 5 percent cash back. (Amazon also operates Amazon Pay for purchasing online goods elsewhere with your Amazon account, and the Amazon Cash service for translating cash into store credit using a barcode, although neither are restricted to Prime users.)
The main con is obviously the cold, crowds, and chaos. But just because Black Friday traditionally means in-store shopping, doesn't mean that many retailers won't offer sales online. Last year, online sales hit 19.62 billion over the five-day period from Thanksgiving through Cyber Monday. So if you don't want to wake up in the middle of the night to battle crowds and wait in long lines, check with your favorite stores to see if you can do it all from the comfort of your home.
Shelfari was a social cataloging website for books. Shelfari users built virtual bookshelves of the titles which they owned or had read and they could rate, review, tag and discuss their books. Users could also create groups that other members could join, create discussions and talk about books, or other topics. Recommendations could be sent to friends on the site for what books to read. Amazon bought the company in August 2008. Shelfari continued to function as an independent book social network within the Amazon until January 2016, when Amazon announced that it would be merging Shelfari with Goodreads and closing down Shelfari.
While Amazon has publicly opposed secret government surveillance, as revealed by Freedom of Information Act requests it has supplied facial recognition support to law enforcement in the form of the "Rekognition" technology and consulting services. Initial testing included the city of Orlando, Florida, and Washington County, Oregon. Amazon offered to connect Washington County with other Amazon government customers interested in Rekognition and a body camera manufacturer. These ventures are opposed by a coalition of civil rights groups with concern that they could lead to expansion of surveillance and be prone to abuse. Specifically, it could automate the identification and tracking of anyone, particularly in the context of potential police body camera integration. Due to the backlash, the city of Orlando has publicly stated it will no longer use the technology.
