A social media startup and a company with a product simply called "Palantir Government" might seem like an odd couple, but its possible that Palantir's interest in Poptip lies in its natural language processing capabilities. NLP is certainly a hot topic at the moment, with AlchemyAPI, Synapsify and Clarabridge all announcing healthy funding rounds in this domain. Social media content without the NLP could still be of interest to Palantir; yesterday, Twitter announced a 46% rise in the number of government takedowns on its site.
