Every metadiscursive phrase or tic bears its own clues as to the writer's thinking. "Of course" means that that you are making an assumption or leaving something unquestioned. "In other words" means that you didn't say it right the first time. What follows "in other words" is what you might have said in the first place, if you had thought of it first. That doesn't mean that you should always go back and eliminate the first formulation of the idea, but you should always at least think about doing this. You could even rewrite the first formulation to make it better and still leave the second. Some ideas need restatement for clarity or rhetorical effect.
I used to use "At the same time, however...." virtually every other sentence. Here the logic is to leave both halves of the contradiction operant. Or "I'm always giving you what you already know first, then I'll spring the new information on you." There is nothing particularly wrong with any of these devices, used in moderation, but it helps to have some self-awareness. I was using the word "entail" a lot a few months ago. When I noticed that I realized that my thinking was orientated toward a certain variety of logical consequences. Once I realized that, I could clarify my own ideas more easily by sorting out different kinds of "entailment" and seeing whether I really needed to use that word so much.
