I am not liking endorsements of skills at LinkedIn. Endorsements make it appear like the non-endorsed skills are not really skills that I have. All of a sudden, a number of my listed skills are under suspicion as they don't have a thumbs up from someone. What happens if I gained that skill on my own time? What if the person(s) I worked with are not on LinkedIn or we are not connected for whatever reason? Personally, I wish LinkedIn had never started this practice.
There is someone who endorsed me for one of my skills that I never worked with. We meet at a networking event but he would never have seen me exhibit this particular skill.
As for now, I am not endorsing anyone's skills at LinkedIn because I see it as a cheapening of ones profile. I don't want to play this game of constantly updating things on social media. LinkedIn is trying to keep people busy at their website.
