Chris Coyier: Words to Avoid in Educational Writing (CSS-Tricks)
And they are:
Obviously (obvious to whom?)
Basically (use fewer words and be clearer
Simply (simple for whom? just omit this word)
Of course (show why it's clear, don't say it is)
Clearly (see above)
Just (meant to be casual but not a good word for casual)
Everyone knows/As we all know (do we _all_ know it?)
However (don't start sentences or paragraphs with it)
So (new paragraph needed?)
Easy (don't assume so)
