The new Profile is the latest in a string of recent feature rollouts at LinkedIn that have been made possible by a rearchitecting of its product development and deployment systems and processes, he said.

"We're now innovating faster than ever," he said.

However, Altimeter Group analyst Susan Etlinger said that the Profile update isn't a revolutionary change for LinkedIn, but rather more of an evolutionary improvement.

"What's interesting is that it brings some of the untapped value of LinkedIn to the front," she said.

LinkedIn's weak spot has been that it's not as fun and easy to use as Facebook, Twitter and other social networking and social media sites, so it's a good move to make the Profile page more enticing and to proactively show people points of common interest with others, she said.
