Beyond that it’s mostly a bunch of folks spending time on LinkedIn trying to impress people that aren’t spending their time on LinkedIn. Which ironically drives away the people folks seem to be trying to impress. Spend time there if you wish, but you’re “marketing” to people that mostly aren’t there.
The whole “influencer” thing on LinkedIn is mostly full of grifters claiming to be experts at things they’re not really experts at. When someone starts off by saying they’re a “top influencer” on LinkedIn I run the other way, quickly. If you have to market yourself as an influencer then newsflash you’re probably not. If you are, you just are.
