All social media lives and dies by engagement. It doesn’t matter if you’re Lemmy, MySpace, or an obscure forum dedicated to ant husbandry, what keeps you alive is engagement from users. This generates revenue from ad sales and sponsored posts.

In my opinion the issue with LinkedIn is the duality of its use. Most users like you and I just create a page, upload our CV, connect with our coworkers and then close the app. We don’t spend time engaged with the site, we’re not moving a lot of traffic and we’re not purchasing services.

So LinkedIn encourages “content creators” to try and bring in views, and then they try to sell things to these viewers. Want to be successful like this person? Buy LinkedIn learning! Want to have recruiters fighting over you? Buy LinkedIn Premium!

Generic content just brings in content and they bill it as career development.

As another user pointed out, most bacteria and other microscopic forms of life don’t really “breath” in the way we think of it. Often they just absorb oxygen from their surrounding environments.

They can be washed away, killed by chlorine (pools), or killed by salt imbalance (ocean). However it’s really hard (read near impossible) to kill them all, and even if you did they exist in our environments naturally and from other humans as well as on things we’ve touched recently. So they repopulate quickly.

There are some arguments that Sodium Laurel Sulfate kills “good” bacteria on our skin.
