There’s a similar network effect problem with Facebook, but it’s a lot easier to leave Facebook because you presumably can still message your real life friends in other ways.
With LinkedIn you can’t leave without also seriously hurting your ability to get in touch with recruiters.
That said, you basically don’t have to spend any time on it after you set it up. Maybe update once a year? So doesn’t seem like that big of a deal.
...not that I've ever had anything useful come from talking to a recruiter. The useful bits have always come through my existing personal network more directly, or through meatspace networking. I shut down my LinkedIn because I basically started to view recruiter emails as spam.
So in my world, having a CV with the necessary keywords (SOX, HIPAA, GDPR, COBIT, NIST SP 800/XX/yy/zz, NIST CSF, etc.) is a life saver because I always have headhunters calling me. I don't see them as spam. I just tell them to ring me 30 days before my contract/extension ends, and they gladly do so, and I stay working like this.
I don't spend more than 10minutes per month, and only to accept/ignore/reply to messages. I use it. I don't let it use me (apart from the fact that they sell my data to anyone who is willing to pay them).
Sure - if you know people that work at the specific company you're interested in then you can just get a referral through them, but if you don't then having a history of email contact with recruiters at interesting companies via linked in is quite valuable and makes it easy to jump to the interview process.
The job market is strong so we (devs) get a lot of email from recruiters trying to hire, and the recruiter quality can vary (generally employees of the specific company are better than hired firms), but in general I think this is a good problem to have.
I don't categorize the person you're replying to this way, but I've definitely seen devs go on a bit of an ego trip because of the recruiter emails they get and then treat them dismissively. A career is long, there's no reason to be nasty to them or cut them off - at some point you might need their help.
I dislike LinkedIn, but have seen very few people walk the walk professionally when it comes to influencing their own workplace to stop using it in some way. I have advised every company I have worked at against using external recruiters, and rarely has it been accepted (even though we always got a lot of candidates from the external recruiters who weren't a good fit with regards to either skills or eagerness).
Props to the article author for actually doing so, and I hope they will remember this and not use LinkedIn when the company they are cofounding has to recruit their N > 20th employee.
Email might be a neutral tool, but not using a tool like LinkedIn is worse because you're restricting your hiring pool to immediate connections. For all its warts, LinkedIn allows job seekers to connect with a wider range of jobs and job posters to connect to a wider range of potential candidates.
The answer isn't to double down on a "it's not what you know but who you know" world.
Most outside recruiters are terrible, we can agree on that. It's a two-fold problem, they give you poor candidates and harm the reputation of your firm by leaving a poor impression of you to them. I'm looking for work right now and had first hand experience of this recently; I don't know if I should feel sad that I didn't get a job that sounded perfect or happy that I dodged a bullet because if the candidate experience was so bad, what would working there be like?
