You probably know Pluck as a company providing a combined aggregator and integrated bookmarking tool, combined with integrated searches at places like eBay, Google and Amazon. The company has gradually expanded into other areas, first with Shadows, which combines social bookmarking with relationships around groups and discussion interacting with the bookmarking rather than the pure bookmarking with tags familiar in tools like del.icio.us. Most recently, Pluck launched BlogBurst as a platform for mainstream media companies to have access to blog content from some of the stars of the niche blogging world. At SXSW, Chris got the chance to chat about all three offerings and how they play into the greater word of information creation and consumption.
