In addition to the points in this article, I've also found real-time chat is much less efficient for deep discussions than email or voice. For some reason, people tend to break up their thoughts and post them as individual sentences. Maybe it's because that's similar to vocal communication - you want peoples' attention as you're speaking and sending what you want to say bit by bit is sort of like "having the floor". Or maybe it's the anxiety that the subject will change before you're done typing. But it's terribly inefficient because typing is slow and it results in people misunderstanding each other due to poorly structured writing. I find discussing significant plans/changes is much better done over email, where you get to craft your argument and make sure it reads well before you make several other people spend their time reading it.
