LinkedIn “Profile Strength”
If you fill the circle all the way up, you advance from “All-Star” to “Baller” but nobody’s ever done it and lived to tell about it. True story.
This has been a mild annoyance for me, as I had no clue how I to fill the circle 100%. Turns out it's not possible. I guess it's LinkedIn's way of telling you that your profile will never be perfect, and that there is always room for improvement. Fair enough.
