This is a visualization of nearly every SMS or instant message I've sent or received since I graduated high school, 1.2 million and counting.

Each row represents a person (across many messaging platforms).`

A colored square represents a day that I communicated with that person.

The darker the square the more messages were sent.

There is no missing data after early 2009, gaps are real lapses in communication.

Several of the top 100 are apps that text me
