Omni

Omni 1:1 Behold, it came to pass that I, Omni, being commanded by my father, Jarom, that I should write somewhat upon these plates, to preserve our genealogy— Again, leading with preserving genealogy, which is a bit different than leading with to teach about Christ. Of course my own motivation for keeping this journal is "to document which days I actually read the scriptures," followe closely by a "to record my incredibly valuable thoughts for my progeny," neither of which is "to teach about Christ.

Omni 1:9 Now I, Chemish, write what few things I write, in the same book with my brother; for behold, I saw the last which he wrote, that he wrote it with his own hand; and he wrote it in the day that he delivered them unto me. And after this manner we keep the records, for it is according to the commandments of our fathers. And I make an end. Chemish is an interesting one—he makes a point of stating that he saw his brother make his final entry, says that doing that is the manner they follow, which implies that he may not have read this whole record before putting down his one comment and passing it on. He is followed by his son, who says that he doesn't know of any revelations or prophesies other than those that are already written, which, to me, implies that he at least read the book. He also makes an interesting update on the genealogy thread—in his mind, it is supposed to be the genealogy of the kings, which they're keeping. He almost implies that he doesn't get the value of the plates he is keeping or why he is doing so.
