Reddit is social media, social news and discussion website, you can sign up and get lots of great content and useful information on this website.
But I would have to say that the website is clustered with lots of information and is so confusing for the new users visiting the website, its very hard to figure out as to where to start from, so I would say that its not user friendly or newbie friendly.
Reddit is free to join and it also does not require the user to enter the email address as well. The website definitely has a huge community and very informative and updated with the current affairs kind of people.
Overall its a good community to be part of if you have lots of free time.
