The mental overhead of switching between - and keeping track of - messaging apps shouldn't be ignored.

Speaking from experience, I have a hard time remembering which specific platform is preferred by specific contacts. It's a minor annoyance, but it's always present.

How many messenger apps do you run, and how many is too many?

For me, the limit is 2. Note that currently I am forced to keep 5 different apps to keep in touch with my contacts.
