Very good review

More than a tool, Mass Relevance is a wish many media companies and brands turned publishers express: That of scaling their conversation strategy to the point where the best content from participants is embedded right into the TV program and live digital cast in real time. Next generation CEO Sam Decker, a veteran in digital marketing, word of mouth, and user generated content, gave me a tour of the platform recently. Sam previously grew Dell.com (consumer) to $3.5B and was founding CMO at Bazaarvoice, the leader in social commerce. From its beginning brainstorming sessions to build the first tool, TweetRiver, Austin-based Mass Relevance currently serves media organizations and brands like NBC Sports, Cisco, Samsung, and Xbox. With a 14-people team and 40 clients, the company is a preferred partner of Twitter media and is working on adding more services and custom technology around the TweetRiver platform. Curation, strategy, visual rendering The deep curation capabilities available on TweetRiver are employed to make sense of existing content volume around an event or program - for example, the Oscars, The Voice [depicted in the image here], or a sports match. The tool allows you to filter comments, in this case tweets, by choosing from a robust set of variables, identifying the most relevant based upon the combination, and posting it to the event site and screen choosing from a series of interesting visualization templates.

Xydo is a new and engaging way to get personalized and custom news from Twitter, Facebook, RSS, and other channels from people you know and trust.

In many ways, Percolate aims to be equal parts Tumblr, Google Reader, and Disqus. Like Tumblr, user content is divided between your own feed–called your “Filter”–and your follower feeds–called your “Brew.” But instead of having to post your own content, Percolate features a steady stream of interesting content, from you and your friends, for you to comment on. Percolate, Brier says as he downs his red eye, currently has six employees, and plans to launch for invite-only beta testing early next week. If any Fast Company readers would like to give it a try, just contact us on Twitter–we have some invites to give out to the first dozen or so who request it.

Maybe you don't have the resources to develop a lot of content, or maybe you're a professional association that wants to serve its members better by being super helpful. Add that there are many more content creators, inside and outside organizations, and you see how curating information as content strategy could be a very elegant option. Noting the evolution on the World Wide Web quickly to show you a pattern that went in lockstep with use. You had forums and discussion boards, many still very active, Web sites, then journals, which evolved into blogs with RSS (real simple syndication) capability to package and read feeds, social bookmarking and networks, and then media sites to upload and view videos, photographs, etc. Each set of tools building on the next, thriving when filling a specific need, and evolving or morphing into something else as appropriate. By now, like most people, you have linked to and shared information, photos, videos, quotes, posts, and stories on your Facebook profile wall, Twitter, blog posts, and other social networks. Real time logs I suppose I'm quite old fashioned to be still using a blogging platform in a blog format to publish content. Many publications that got a similar start have moved to more of a magazine format based upon blogging tools. Many blogs have moved to more real time publication tools. Moving away from blogs and into easy-to-use real time publication and bookmarking tools, you now have a couple of solid options. Tumblr is a re-envisioning...
