[scrubs]

I'm guilty of sin two. And I can see the op's point. So I can amend, improve.

One sin that ought to be included replete in CS, math, and physics papers my English writing instructor made me stop: parenthetical phrases. Excessive footnotes are another variation.

Readers are not interested in the author's breadth-first association of one fact to 87 other facts.

Fixing this requires two things: knowing associations is certainly good. But know what's for you and what's for the reader. Second, know the point you're trying to make and nail it without bringing in half baked facts or edge cases.

In my papers I cut all that out. I either connect and explain clearly or I omit.

Re: grandmothering: I totally agree with op: if I'm a specialist in the area it's not value add. Like too many Ted talks it's people telling the in crowd what they probably already agree with. If not a specialist it's inaccessible. Either way it's bad, it's waste.
