Praized Media, recognizing that social-based media has largely moved from the blogosphere to social media sites during the past two years, has now rolled out “Needium,” a new semantic search site that crawls Facebook and Twitter for specific leads.

“A lot of the conversation in blogs now occurs on Twitter and Facebook,” says cofounder Sebastian Provencher. Using social micro blog sites — the “statusphere” — is “so much easier than blogging,” he says. Provencher adds that the new move is not a 180-degree change. The company has been taking half steps toward a Needium-like product since its launch, for instance, adding real-time search.

Needium will specifically offer consumers an outlet to search for explicit things like services and restaurants, or implicit things (“what’s fun in Boston?”). It also gives merchants the ability to respond with offers after their names are “surfaced.”

Ten to 20 categories are initially being launched, ranging from obvious travel-related categories to smaller ones, such as jewelers. A consumer might ask where to fix a broken watch, says Provencher.

Praized, a seven-person outfit based in Montreal, says it will continue to support its original blogs-based “social media stack”for enterprise clients such as YPG and Examiner.com. In addition to supporting licensees, it will also eventually develop a destination site of its own.
