Country-specific local job boards are best. Big tech companies (LinkedIn, Indeed, Glassdoor) are terrible for this purpose. Always apply directly on a potential employers' website, best through email if they accept that. Even printing your application and sending it by mail is a far better option than applying through LinkedIn or Indeed.
It's still used for job hunting and recruiting unfortunately. I got a real message from a real recruiter for a 5k+ employee software company on it just last week. My friends and colleagues dealing with layoffs have had to update their profiles. :(
Sadly, LinkedIn has replaced email for initial contact after fairs or in-person client meetings. New real-world contacts look you up on LinkedIn and then use it to ask for things like your email address or mobile number. Because of this, I'm even verified :-(.
Even though I use LinkedIn basically the same way Internet Explorer was used in 2009 (purely as a Firefox or Chrome downloader but not for browsing). LinkedIn is my initial contact details exchange, but not the platform to communicate.

It is. I basically get zero useful input. Just biased, shallow rubbish. If there is valuable content it is usually cross-posted from authors who also run blogs I already follow.
