Teach Me How to -Dougie- Viral Loop.
What you see here is a work of art for making viral loops.
The page leading up to this asked me to _confirm_ that someone had endorsed me. I accepted the endorsement (adding it to my profile).
This page uses some decent semantic analysis to generate 'Skills you might Endorse', and a one-click way to generate a 4x viral loop (not to mention all the other mechanisms via 'see more' and loading up more endorsements.
Performing actions here also help improve the algorithms. If one person tags a user with a skill then you can present the same tag once added to the profile to other users and have a high likelihood of success.
And at the end of the day LinkedIn will have a much better way of finding strong candidates with specific skills; users will have more profile content, etc etc.
