Twitter Benefits: It's an unrivaled source of information and connections with people whose interests are similar to mine.

Twitter Costs: I look at it all the time.

Net value added: Negative (probably). While it's impossible to quantify what I've paid in time and attention lost, I'm highly suspicious that these costs outweigh the benefits of information discovery.

The decision: I'm deleting all Twitter apps from my iPhone, the device on which I check Twitter most often. The fact that it seemed so crazy to do so makes me even more curious how this experiment will turn out.

I am not ready to quit Twitter entirely. Just ready to evolve how I use it. I'm leaving it on my Mac and iPad(s). For now.
