Its a platform for people with low self esteem to dream about what their lives could have been. For older folks to remember the past. For the average guy/gal to keep tabs on old flames.
And most importantly a place for jackasses and rich people with various complexes to show the world how great their lives are.
And Facebook is great at figuring out your weakness. For me for example, Facebook became a window for re-imagining my life in college.
No thanks. The trip down memory lane is fun every once in a while but the old picture catalog in the closet has morphed into an insidious entity, always beckoning you back. My phone vibrates, someone posted a new picture of you from 5 years ago and 50 people like it. Remember that day? All those people. Dont you?
Fuck that, I'm done being screwed with by a platform designed to give you your fix.
