By late 2013, however, The Huffington Post was taking steps to operate as more of a "stand-alone business" within AOL, taking control of more of its own business and advertising operations, and directing more effort towards securing "premium advertising".

The site offers news, satire, blogs, and original content and covers politics, business, entertainment, environment, technology, popular media, lifestyle, culture, comedy, healthy living, women's interests, and local news.

Alternative medicine and anti-vaccination controversy
Dana Ullman, a notorious homeopathy apologist, actually has a regular blog over at HuffPo. For those of us who follow such things, the start of his blog there marked the point of no return for the Huffington Post – clearly the editors had decided to go the path of Saruman and "abandon reason for madness." They gave up any pretense of caring about scientific integrity and became a rag of pseudoscience. 
Commenting in 2012 on increased conservative engagement on the website despite its reputation as a liberal news source, Huffington Post founder Arianna Huffington stated that her website is "increasingly seen" as an Internet newspaper that is "not positioned ideologically in terms of how we cover the news."  According to Michael Steel, press secretary for Republican Speaker of the House John Boehner, Republican aides "engage with liberal websites like The Huffington Post [anyway, if for] no other reason than [because] they drive a lot of cable coverage."  Jon Bekken, journalism professor at Suffolk University, has cited The Huffington Post as an example of an " advocacy newspaper ". The Wall Street Journal columnist James Taranto mockingly calls it the Puffington Host , and Rush Limbaugh frequently refers to it as the Huffing and Puffington Post . 
During the 2016 U.S. presidential election, the Huffington Post regularly appended an editor's note to the end of stories about candidate Donald Trump, reading: "Donald Trump regularly incites political violence and is a serial liar, rampant xenophobe, racist, misogynist and birther who has repeatedly pledged to ban all Muslims—1.6 billion members of an entire religion—from entering the U.S." After Trump was elected on November 8, 2016, the Huffington Post ended this practice.
