I'll have to tell my friends that they're writing their papers wrong.
Of course, it does happen that credit gets shared unfairly, or that the better writer in the group (or the best writer that someone in the group knows!) gets landed with the bulk of the copy editing, if not all the writing itself. These people are just people.
But the fact remains, if you can't convey your ideas to someone else, they're pretty useless. Who
hasn't worked with someone inarticulate? Where after a whole bunch of work's been done they say "No no no,
that's not what I meant!" to an audience of stunned faces all silently saying "Well, it's exactly what we all heard you say

"
