One question: after writing the sentence “I really got a lot out of the article.”, I wondered: is this extraneous? Is this clear? Am I saying precisely what I mean? And I think, yes, I meant exactly what I said, and I went into detail in the following sentence. I am just curious what you think.
Your writing is not clear to me. Using the word “really” is extraneous. Using “I think” is also extraneous; I assumed these are your thoughts.
As the author notes, replace “it” with “the article”, or better yet a specific quote or idea distilled from the article.
Helped “my write” should be helped “me write”. You use two -ly adverbs, which could be avoided by restructuring the sentence.
You also have a list of two (succinct and clear) and then a single item (better understood). Consider breaking these two thoughts into separate sentences.
> Your writing is not clear to me. Using the word “really” is extraneous.
What's not clear? He said the article helped him, it seems pretty clear to me. The "really" was for emphasis, which is fine.
> Using “I think” is also extraneous; I assumed these are your thoughts.
"I think" indicates the degree of certainty. The author is uncertain but deems it likely.
> As the author notes, replace “it” with “the article”, or better yet a specific quote or idea distilled from the article.
The previous sentence says "the article", and the next one says "it" to avoid repetition. Saying "the article" twice would be awkward.
Very odd feedback, given how obviously out of place the corrected sentence would look.
When you write anything, you have to assume your audience is at some baseline of understanding the topic. Otherwise, every software article would have to begin by explaining what a computer is.
In an article about optimizing web performance, it seems like a reasonable assumption that the reader would would already understand what "HTTP" means even if they don't recognize the abbreviation "TTFB."
