Your writing does tend to be verbose-- the amount of interesting surprise per amount of text is low.

Part of the problem seems to be repetition among articles as well as within them.

Judging the amount of redundancy needed and then supplying good quality redundancy is a hard problem, and I think most people just have a habitual redundancy level. (Mine may be too low.) I haven't seen an overt discussion of how to do redundancy well anywhere.
