Why? The benefits no longer outweigh the costs for me. We are moving into different times and it became clear to me that investing time into the platform does not make sense. In this article I explain why, the plan, and the alternatives. Will you join me on this ride?<\/p>\n<h2 id=\"how-it-began\">How it began<\/h2>\n<p>I started using LinkedIn on 20th of October, 2007. Or at least, that&rsquo;s what the platform says. Where to find this? Click on Settings, Data Privacy, Manage my activity, and go to the last page. An interesting thing with LinkedIn is that everything is buried below at least 3-4 clicks. Anyways, I guess that we can say that with 18 years my profile is an adult now. Time to let it go do its own thing ;-)<\/p>"},{"title":"My website is not being indexed!
