It's always functioned for me, but it's not bag and doesn't really work for me. I've got a very small batch of friends that I care to stay in touch with and those folks I call, visit, email, get together with, etc. Barring the Syrian Revolution, I don't think it's of much value...especially in the U.S., even more so since it seems they played a significant part in the dissemination of actual fake news, info, stats, etc. that landed up with Fuckface von Clownstick as a White House resident.
Facebook might be one of the worst things to happen to our nation and world, if merely by proxy of any and assistance it may have inadvertently provided to Trump's campaign. The same could be said of CNN and other mainstream media outlets that in a supposed effort to have him sink his own ship gave him hours more free airtime than they did other candidates.
So, NO Facebook isn't fucking work for me.
