My boyfriend's dad, who is not technical whatsoever, endorsed me for git. I'm pretty sure he just saw the word git and thought, "Hehe, she's a git!"
I think the problem too is that LinkedIn offers people the path of least resistance to endorse people. Occasionally I'll see a message at the top of my profile saying, "Endorse X for Y & Z" and a button to approve it. I'm sure more times than not, people just approve endorsements without giving it a second thought.
Are you telling me that you only get "meaningful" add requests? My friends don't often bother (the feeling is mutual), but the more desperate acquaintances seem to seek me out nonstop.
I'm probably in the minority when it comes to how I use the network, but I've also found that I get a lot less noise from it than most people. I can't say if these two factors are correlated at all, but it stands to reason that they would be.
Some people (undefined process) are given an endorsed skill (eg. Python). They can now endorse anyone in their network for python. But they cannot endorse anyone who claims a skill in 'goat herding'.
Now they have meaning as you can only endorse someone for a skill you have also been endorsed for.
My former boss had added 'Oracle' as a skill. I didn't know until LinkedIn asked me to endorse it. He's not even a technical guy, so I've no idea why he had added it but he's actually been endorsed for it by other business owners.
They really need to figure that business out. Even a simple, "How do you know this person?" would suffice, allowing people to determine the weight of that endorsement on the relationship we have.
...or perhaps the recruiters sending email such as "I see you have worked with purely with linux and mysql, how about you applying for this 100% microsoft-stack company as a sharepoint/exchange professional." That might not be linkedins fault the recruiters seems stupid, but it should be in linkedins interest to not annoy me with such crap.
And yet I am still getting empty endorsements.
