Search engines are transferring their love from content farms to social media – While they probably resent the content farm title, EzineArticles, Hubspot, and the like were the primary target of Google's Panda/Farmer update and saw traffic drop off a cliff. Meanwhile, the major search engines are doing everything they can to show results that originate from social media sites. Even if you don't plan to fully engage on these sites, you should have a monitoring system in place to see what is being said about topics relating to your business.

Google's description of low quality sites they were targeting stated, "sites that contain content copied from other sites" which is pretty much the backbone of all of these sites. Adding to the pain is that these sites are used by thousands of individuals and agencies as an outlet for website related content.
