As I write this there are two comments that have been downvoted to the bottom for expressing how difficult the post is to read. They draw attention to the post's textual interface, albeit perhaps sarcastically ("Is the new web better at UX than this? That was painful to look at.").
Not only is theirs a serious concern, but it speaks to the main issue of the post, for it reminds us that like web interfaces, even text has accreted arbitrary rules to interpret it. Take the apostrophe for example, it is for most purposes superflous as one can tell from context whether a word is plural, possessive or a contraction. Well, I can tell the difference, cant you?
The original post is saturated with consistent, but by no means universal and certainly not empirically-derived, pre-conceived rules for communicating textual content: the date posted is in italics; the site name is bracketed and bold; the post name is bold; links which serve a sorting function are colored, underlined and bracketed; a presumably copied email prefaces the actual post in italics with each line itself prefaced with a less-than-sign; and most importantly much of the post is composed of incomplete sentences ("A web where...").
We allow ourselves to bend the rules of grammar. And as we bend them, we adapt to the new general rule.
We are all familiar with the english teacher's common correction of a misplaced object: "It's 'He and I went to the store', not 'Me and him went to the store'". This "rule" has been so often repeated, that most days I hear college-educated individuals perform the inverse, substituting the nominative for the objective case, as in "Bob critiqued the web page with Jack and I." What is interesting to me is apparently the act of replacing the nominative with the objective also occured in the Latin language around 200 AD (and it's a common act in children). So, if we create our rules for grammar empirically and not not arbitrarily, we can look at saying "Me and Jack did something" as acceptable because it has a natural precedent.
Which is all just to say that communication as a web form or in paragraphs is subjective and organic. Differences in type should be no more surprising than differences in human ethnicity.
