Well, one thing I noticed was an inconsistency with "thy" and "thine". Which one you use depends on if the following word starts with a vowel, with "thine" before vowels and "thy" otherwise. For example, the article has "in thy own case", as well as, "output thine data". Some investigation seems to lead me to believe that this a more a matter of style, but I still think it sounds wrong.
Quite correct. Spoken English abhors glottal stops, and written English reflects that. Still, it is not as consistent as one might wish in the written record, humans being about 85% logical and 15% irrational and language reflecting that, &c.
