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.
Throughout the summer of 2018, Vermont Senator Bernie Sanders criticized Amazon's wages and working conditions in a series of YouTube videos and media appearances. He also pointed to the fact that Amazon had paid no federal income tax in the previous year. Sanders solicited stories from Amazon warehouse workers who felt exploited by the company. One such story, by James Bloodworth, described the environment as akin to "a low-security prison" and stated that the company's culture used an Orwellian newspeak. These reports cited a finding by New Food Economy that one third of fulfilment center workers in Arizona were on the Supplemental Nutrition Assistance Program (SNAP). Responses by Amazon included incentives for employees to tweet positive stories and a statement which called the salary figures used by Sanders "inaccurate and misleading". The statement also charged that it was inappropriate for him to refer to SNAP as "food stamps". On September 5, 2018, Sanders along with Ro Khanna introduced the Stop Bad Employers by Zeroing Out Subsidies (Stop BEZOS) Act aimed at Amazon and other alleged beneficiaries of corporate welfare such as Wal-mart, McDonald's and Uber. Among the bill's supporters were Tucker Carlson of Fox News and Matt Taibbi who criticized himself and other journalists for not covering Amazon's contribution to wealth inequality earlier.
