My guy, this entire community is based around people who post shit like this all the time in complete earnestness. I dont think that its as "obvious" as you do that this particular case is satire. But even if it is, that is only confirmation that plenty enough people post shit like this being serious that there is something to even satirize about it. So, whether or not this specific guy is making a joke, my comment and question about serious LinkedIn posts like it still stands. But you in particular who calls people idiots for participating in the purpose of the community they are in, and acts like a smarmy asshole about it too... you can fuck off.
