Completely agree with Tom on this one. LinkedIn can be a great part of your branding arsenal, and is essentially a business version of 'Facebook'.
I always recommend to keep your LinkedIn profile and details up to date. From a recruitment perspective it is used as a key tool (often over used and relied on...but that's another topic altogether!) and something that can be used to scout out talent.
With the Xmas holidays coming up it could be time to brush up your profile and showcase your brand to the LinkedIn world, as 2017 could be the year of your dream job.
As a specialist in personal branding, I'm continually amazed that many people don't take full advantage of their LinkedIn account. While your LinkedIn profile is only one tool in your personal branding arsenal, it is a key component.
