I would extend this even further: there are a lot of things that get between the reader and the message of the writing. It is author's job to remove as many of these obstacles as possible while keeping the text enjoyable and colorful, fresh and juicy.
These things include, in my humble opinion, but are not limited by:
- *adverbs* (see S. King's "On Writing");
- brackets;
- excessive passive voice;
- complex sentences, as well as too lengthy ones;
- placing the subject too far from a predicate.
