I'm looking for suggestions on the endorsements of skills in LinkedIn. It will be used on a corporate platform where profiles have 1 or more skills.
Ideas so far are: "+1" or "like" (with a thumb up). In my opinion is the "+1" not very clear on what it means, and the "like" feels to informal to me.
Also thought about the "star", but we will also be using a "star" in the platform,to mark documents that you like. I'm worried that this will be confusing.
Do you have a suggestion on graphical representation to endorse someonse skill?
Background; I'm working on a corporate knowledge platform, where profiles exist. A user can add skills to his profile, chosen from predefined skills or fill in his own. Other users (colleagues) can endorse your skills.
