The interview was pretty interesting. Sacca's description of how they make it hard to follow what's going on, even though they know first, sums up why I don't use Twitter. Twitter always feels like I'm walking into the middle of someone else's conversation or inside joke. I rarely have enough context to engage, but people who like to just be loud, or talk to themselves, or don't have a clue can go to town.
Maybe I'm doing it wrong.
