At first, during reviews, I used sentences like: [I find that to be a little on the slowish side. You might want to consider maybe removing one of the adjectives] (Ok, this is a bit of an exaggeration, don't go dig for actual quotes ) Little by little I managed to remove the "I think", "I suggest", "It seems to me". First I repeated myself that it was obvious it was just my opinion. Then I started repeating myself "It's not optional, this should really be changed and not saying so in clear terms would be harmful". Finally I've managed to be a bit more assertive during the reviews. I use comments closer to [Too slow, remove that adjective] or I directly dare to suggest whole sentence replacements. I think my opinion is clearer this way and more helpful. I'm also pretty sure that if the writer didn't agree or understand he'd let me know. Now I'm thinking about the next step. What am I doing during reviews that could be done better? Should I comment on the story when the style isn't yet right? Should I mark a mistake every time It appears in the text instead of only the first two or three times? Should I comment the final results before the review instead of at the end? Did you have similar evolutions of your reviewing style? What were the biggest changes?
