Different people have different communications styles, and resolving that is always tough. But there are definitely those who communicate poorly in any medium -- and I find that often they're the ones who like media where they don't leave a trail that can be pinned on them.

There are are advantages to the "quick call", and some people definitely work better that way. But I much prefer written communication: not only do I get to refer back to it, but it's more asynchronous, freeing me up considerably.

"Let's talk" often seems like a barbarous imposition on my time, that I have to hear it right now and make any decisions while you're staring at me. I try to keep in mind that they just have a different communications style, but that's not always easy.
