I enjoy reading Reddit, Quora though not on the professional level. LinkedIn is the only one I use business wise, the rest are obnoxious and pointless; like those shitty celebrity magazines in dentists which just spams the mind. They draw customers one really does not want anyway, looking for assistance rather than pay decent $$$.
Facebook - A.I is as bad as Bidens memory - I stated "Kill 'em All" the other week. Was in regards to an image of Metallica back in 1984 was when their album Kill em All was out. I got a community standards warning, I tried to state it was incorrect, though the service wouldnt work either to reason to the almighty "Standards Board of Morons".
Instagram - That is where narcissistic people goto make $$$ of of other narcissists
TikTok - Watching stupid people do stupid crap, or some kind of essential "lifeHACK". though is common sense.
X/ FKA - Twatter - Pointless, I never have seen any use of it, post a limited amount of crap for others to crap on about.
YouTube - Meh, why advertise how to do something when you are in the end, demonetising others in the field.
That is my 2.5 Cents due to inflation rounded off to 5c. So anyway, others may have some use I dont.
