From TechCrunch:

LinkedIn, a social networking website primarily focused on business connections has added a section to their site that allows users to recommend service providers — a yellow pages based on user referrals. From web designers to doctors, users rate service providers in a thumbs up, thumbs down voting system similar to Digg.

Here’s another article article with more:

In the case of LinkedIn's directory of service providers, users can search narrowly for services recommended by friends, or they can widen their search to friends of friends. Failing that, a global search capability is offered to allow users to search across the full LinkedIn network.

Making the system work will depend on whether LinkedIn users bother to write recommendations for other businesses, building on an existing feature within LinkedIn that encourages colleagues to recommend other colleagues.

It also could draw in new users. Most LinkedIn members currently are executives, professionals, sales people and other office workers. The new directory could attract trade workers.
