Social news sites pop up all the time. Some of them die out after a brief stay, others flutter along for a while, and a few prosper. In many ways, it is a catch 22. A social news site doesn't become useful until it gains a solid community adding and voting on links, but it is difficult to gain a community if the site is not useful.
The most popular social news sites are Digg, Propeller (formerly Netscape), Reddit, and Newsvine. They each have a strong community and a different look and feel. Digg leads the way as the most popular social news site, but that doesn't mean it is the best social news site for you.
The best way to pick a social news site is to find one that matches your interests and has a look and feel that you are comfortable using. Each of the sites mentioned in this article are general social news sites, which means they cover a large variety of topics. But some social news sites may specialize more in certain categories while being light in others.
Digg is the most popular social news site with a variety of topics. It has an easy-to-use interface and new users can be up and running in no time.
Propeller was formerly a part of the Netscape website. It's interface is a bit more busy than Digg's, but it does have a handy control panel that will list out related articles while viewing a specific article.
Reddit is the no-thrills social news site, and also very popular. It is plain bordering on downright ugly, but it is very easy to use.
Newsvine is a social news site following a newspaper-style. It is fed by news feeds like the Associated Press. It also allows users to write their own articles and create their own columns.
