Earlier quoted context omitted.
If the author otherwise (that is, first word capitalization issue aside) writes grammatically better than >99% of other internet writers, I submit that you can grant them this one shred of self-expressive style. Goes pretty well with the terminal user theme, to boot. It's pretty clear she pays mind to grammar and cares about its proper usage more than most.
I did not say anything about grammar or even punctuation (in general). I have voiced a specific concern of a complete disregard of a proper capitalization. If you call it a "self-expressive style", well, it is your opinion and, of course, you are as entitled to one as everyone else. However, I highly doubt that most people would agree with your characterization of this as a "style". I welcome diversity of self-expres…
I could be wrong. Oh, well.
You might not have brought them up, but I largely (if not only ever) make the criticism regarding capitalization within contexts concerning grammar/punctuation or conveyance. And, given everything else in the article, I think it conveys pretty all right :)
