the cat pictures were admittedly bad. the memes were worse. but what really permanently turned me off was the lack of filters, combined with a disturbing level of mass ignorance.
i was hooked up to a number of "libertarian" type political movements, most leaning towards the socialist brand of libertarianism (anarchism). occupy, idle no more, groups against tar sands development and other protest groups with similar purposes that organized large protests and generated substantial interest.
i'd guess that roughly 75% of the articles that i'd read that had gone "viral" within that political spectrum were absolute nonsense. the stuff on gmos was particularly illiterate. and, it would just get shared by dumb hippie after dumb hippie after dumb hippie. it's the perfect example of how lies can become truth if they're repeated often enough - which in this case means if they're shared over enough feeds.
i reacted, of course. you send out crap in your feed, i'm going to correct you. but, what it lead to was a lot of interpersonal tension, accusations that i wasn't on "their side" and just general close-mindedness to criticism. the meme was authoritarian truth; how dare i challenge it with my puny citations!
what i learned was that social media isn't a replacement for anything - it's merely an evolution of the mob mentality. it reminded me of how important good journalism really is, and why it can't be tossed aside as a relic of the past.
i think that free-thinking people ought to be very cautious of how social media might shape social movements in the future, mostly for the worst. it really pushes a conformist mob mentality, with little interest in fact checking.
i think we can probably blame the anti-vaccine campaign on social media.
i fear it's just the beginning.
