LinkedIn recently combed through its massive user base, exclusively for CIO.com, to identify the most active and influential users in the IT industry. The professional network narrowed down the results to members with the most followers, who list IT as their primary industry. LinkedIn paired the list down further by focusing on individuals who regularly publish on the platform and excluding users who don’t list English as their primary language or are in a career transition. The final nine members all gave LinkedIn permission to be included in this roundup. If you’re not following these IT pros, you’re missing an opportunity to learn from the technology leaders who most effectively leverage LinkedIn to grow their reach and advance their careers.
(Editor’s Note: Seven of the nine LinkedIn members identified in this slideshow are “LinkedIn Influencers,” a designation given to approximately 500 professionals who were invited by LinkedIn to publish on the site, and as such, their follower counts are public. The last two members mentioned are not Influencers, and therefore, their follow counts are private and are not included.)
