The CEO of one firm I worked at wrote emails totally in bullet point format.

Made it much easier to read and you could just reply with:

> bullet point

response

which made life much easier

I love terse text communications most of the time (Slack and email at least). So much clearer. And easier to respond to.

I think we've all worked with someone who (I imagine subconsciously) feels the need to make things longer without actually adding more information in there, and it just makes everyone's day a little harder.
