Alternatives to Reddit, Stumbleupon and Digg include sites like Slashdot, Delicious, Tumblr and 4chan, which provide access to user-generated content. These sites all offer their users a way to publicly share photos, information and links.
Social news sites provide a user-generated collection of news stories, images and links to other Internet content. Some sites, like Reddit, allow anyone to access the content without membership. Others, like StumbleUpon, is a membership-based social bookmarking site that allows users to save and share links. Some alternates to these sites include Slashdot, a news site where users must first submit their content for editorial review, and Delicious, a social bookmarking site like StumbleUpon, that allows users to curate a collection of links for public or private use while also providing social media networking tools.
Other alternatives that provide user-generated content include Tumblr and 4chan. Tumblr is a microblogging site that allows users to post images or brief pieces of information on a highly customizable platform. 4chan is an imageboard where anonymous users can post and comment on photos. Because users on 4chan remain anonymous, unlike Reddit and other account-based sites, there is no way to message other users or develop a social network with them, as explained by the Washington Post.
