Casey Johnston, writing for NY Mag:
Unfortunately, chronological order doesn’t scale well. Once a medium or platform has had its here-comes-everyone moment, the stuff you actually want to see gets buried in an undifferentiated stream — imagine a library organized chronologically, or even the morning edition of a newspaper. People are doing too many things and they are happening all at once, and the once-coherent experience of people using a platform unravels into noise. Who among us hasn’t logged into Twitter only to find friends one-upping each other with meta-meta-meta-ironic jokes about something that happened five minutes ago, and no longer is anyone actually mentioning the thing they’re joking about? Who among us has not followed someone because of a really excellent viral photo or tweet, and then hundreds of posts later it’s like Oh my God, stop talking about your cat, or your car, or your loneliness?
Really good rundown on the idea of “feeds” and what happens when you get too big.
