LinkedIn, one of the most popular social network services on the Web prior to the arrival last month of
Orkut, has just announced the addition of a new feature that allows users to browse the networks of people on their network, it's no co-incidence that this comes weeks after Orkut's release. Orkut provided this feature as standard when it launched. It will be interesting to see where these guys (not forgetting
Friendster) manage to take this as they raise their games now that the need to innovate and compete has gotten more acute.
