I personally found it too informal; I found the numerous non-technical remarks about how "boring" TCP off putting, tbh.

That said, I understand that the author added these in an attempt to make the article more enjoyable. I also appreciate the fact that some readers will indeed find these additions enjoyable. To each his own.

Username checks out. Joking aside, english is a very complex lanuage man and his (eg. "We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable rights") in contexts such as these do not indicate gender (though they may hint at the gender of the author). Only when speaking in the specific do gender pronouns mean anything. (eg. "She came up to me and said", "A group of men came in yesterday")
