I tried creating a profile by logging in through LinkedIn.
I successfully logged in (twice), but at the end received an error: <my email> is not allowed to access this application.
I like the idea, will probably create a profile the old-fashioned way.
Update: definitely not a fan of the date picker. Extremely tedious to click my way back through the years.
Update^2: and the date picker keeps converting a selection of January 2013 to December 2012.
