Disqus is a blog comment hosting service for websites and online communities that uses a networked platform. The company’s platform includes various features, such as social integration, social networking, user profiles, spam and moderation tools, analytics, email notifications, and mobile commenting. It was founded in 2007 by Daniel Ha and Jason Yan as a Y Combinator startup.
Disqus ranks #1 in Quantcast's U.S. networks with 144 million monthly unique U.S. visits Disqus is featured on many major publications, such as CNN, Daily Telegraph and IGN and about 750,000 blogs and websites. It competes with IntenseDebate, Livefyre and Echo.
Disqus was first developed in the summer of 2007 as a Y Combinator startup headed by Daniel Ha and Jason Yan, both of whom were undergraduates at University of California, Davis. Disqus was first incorporated and launched on October 30, 2007.
In early 2011, Disqus raised $10 million in funding from North Bridge Venture Partners and Union Square Venture Partners.
In November 2010, shortly after celebrating its third anniversary, Disqus announced hitting 200 million unique visitors/month. Seven months later in May 2011, Disqus announced approaching 500 million unique visitors/month, in addition to consistent 500% traffic, user, and community growth for the previous year, bringing its total counts to about 750,000 websites and 50 million registered users
According to a March 2011 study by Lijit, Disqus is used by 75% of websites who use a third party commenting or discussion system.
Starting in November 2010 Disqus began officially offering three add-on packages for websites: Plus for $19/month, Pro for $199/month, and VIP starting at $999/month. In mid-2011, the Plus package was removed and Pro was increased to $299/month.
Both the Disqus website and comment system were translated into more than 60 languages in 2011. With the introduction of the new Disqus in 2012, language support dropped to 7 languages and even though Disqus accept applications for new languages, only one such has been added since bringing the current number of supported languages to 8 as of 2013[update].
Criticism and privacy concerns

As with other embedded web widgets such as like buttons, the Disqus widget acts as a web bug which tracks a users activities, even when they are not logged in, across different sites that use the Disqus commenting system. Information tracked by Disqus.com, which may be disclosed to 3rd parties, includes pseudonymous analytics data such as a users IP address, their web-browser's version and installed add-ons, and their referring pages and exit links. Although this data is referred to by Disqus as "Non-Personally Identifiable Information", such data, when aggregated, has been shown to be usable for de-anonymizing users.
Users wishing to avoid these issues may opt to install a privacy-enhancing web browser extension, such as Ghostery, NoScript, or DoNotTrackPlus, which identify widgets such as Disqus as web-bugs, and allows them to be blocked; this renders Disqus-powered commenting sections unviewable.
Disqus has also been criticized for publishing its registered users' entire commenting histories, along with a list of connected blogs and services, on the publicly viewable user profile pages. The option to keep profile activity private was later added.
Disqus also has been criticized for not giving users control over who follows them. Any user can follow any other user, but a user being followed cannot control or block who is following them. This allows the system to easily be misused for harassment purposes.
In the event that Disqus shut down, hundreds of millions of comments would be wiped away from a wide range of sites, since by the very nature of the service, comment content is not being managed locally by sites implementing the service. However, it is possible for site admins to export all of their comments as an XML document which can then be ported into other commenting systems.
