Through Endorse.me, you can collect all of your endorsements in one place and share it with whomever you want to and whenever you want to. You can either sign up through LinkedIn or Facebook, or separately. The site is very useful for those who need to gather credibility for their works and show it off to new employers, especially freelancers.
By signing up through either of these social networking sites, you can import your contacts and request them for endorsements. You can also approve or disapprove any of the endorsements from your contacts. You will get a separate page, which you can then share with those to whom you want to show your endorsements.
There is a “recommendation” section on LinkedIn, however, Facebook does not have any such facility. Orkut, another popular social networking site, has a section on “testimonials” which also works as a “recommendation” section on LinkedIn. Through Endorse.me, you can fill that void on Facebook and share the link to your page with your online contacts.
