Voci.us (formerly “News Talk”) is an ad-supported, web-based comment platform for daily news content. Vibrant real-time conversations and dynamic curation of news stories empowers people to expand their social networks and personal expertise about topics important to them. This improved capacity for discussing and sharing information addresses three problems vexing the news industry: inadequate online community engagement, poor topical search capacity on news sites, and scarcity of targeted online advertising niches.
