Linkedin is some weird platform that is usually thrust upon an individual when they are trying to enter the job market. I actually landed my first internship based on my Linkedin page and can say when you are young and you don't have much experience you will set yourself apart if you have a nice profile. Having a nice profile can be accomplished fairly easily. Use a nice headshot. Add your work experience and just basically copy someone else that has a great profile. Most young people will not even do this so if you know who is going to be interviewing you this could put you over the top if you add them and send them some message. After you get a job all you have to do is update once a year or if you change jobs.
Linkedin as a social media platform is just flat out a waste of time. Everyone just copies each other's posts and there is no real creativity because it is all corporate life and people trying to impress strangers. This is like most social media but this is taken to a different degree. Now, I basically post on Linkedin every single day. It has the best organic traffic and has been a great way for me to grow my podcast. Most people scrolling Linkedin are at their job trying to look busy so I try to make content for them. I find it hard to believe that more trolls haven't gotten on the platform to mess with people. It seems like the perfect place for them to do that sort of thing. It's an interesting platform I guess. If you really want to meet someone you are a message away and it is a lot harder to find people's other social media. It has its benefits but there is no reason for someone to be on it more than once a week unless you are making content for it or trying to find a job/network. Most apps are a waste of time but at least with other platforms its entertaining or funny. Almost all the content on Linkedin can be found in any sales book.
