I used to subscribe to the idea that facebook helped you stay close to friends and family. But the issue is most of the friends and family who I want to hear from and wants to hear from me have too much going on to really be active. So the remainder of facebook is peripheral contacts who think that by posting someone's else content (a meme, a political thought, a call to action, whatever) it's somehow valuable to everyone else. I hear marketplace is useful and is supplanting craigslist. But when I look at it, it's full of off-site ads for products I have no interest in buying. Very little of it is actual neighbor to neighbor legitimate items for sale. I deleted the app from my phone over a year ago and haven't really missed it. More importantly, I really fail to see the value that facebook provides.. can you imagine if they'd really pitched to VC's what they've become they'd ever been funded in the first place? "Hi, we are going to attract users who used to forward email spam to all their contacts in the CC line and give them a place online to collect all their BS on one convenient place and then we're going to market all sorts of crap at them."
