Active voice: Using "I" to show my contribution and "we" to include the audience?
Apart from issues of singular versus plural first-person in active voice, ... it is often possible to use third-person (active), simultaneously shorten the sentence, and perhaps only refer to the objects, phenomena, and processes in play. E.g &quot;Application of procedure X to stuff Y produced whatever-Z...&quot; (Or &quot;Procedure X applied to stuff Y ...&quot;)
That is, often, &quot;unwinding&quot; the grammar can show that there are redundant or functionless phrases, which can be dropped, and in fact clarify.
(In my field, mathematics, in English, in the U.S., there certainly is a tradition to use plural first person, but, truly, I've found that often unwinding the grammar allows shortening. And, often, unwinding allows active voice rather than passive, and shortens and simplifies.)
