Re:Is LinkedIn using a URL strategy I don't know about...? by uams on Friday September 14, 2012 @05:12AM (#4520851)
I recognize the optimizely part. Good guys so I'm glad they've got LinkedIn using them to AB test.

I was able to duplicate it on the Profile Completion section as well. I didn't have as many '_*1's. Maybe my profile was more complete then yours? It seems like an odd way to keep track of progress regardless.
