I'd always assumed the primary goal of LinkedIn endorsements is the same as every other email I get from LinkedIn, to keep user engagement with the site - and based on the number of colleagues I see accepting them, I'd say it's been pretty successful at achieving that goal for LinkedIn.

LinkedIn makes loads of money from their recruiting products. They likely care as much or more that you have a good profile that recruiters can search as that you spend time on the site.
