I find the programming has made my writing more structured and precise. It has also made me less forgiving of writing which is disorganized and imprecise. (This week, that was technical information on the PayPal developer site.)
Like in writing on paper with pen. These qualitative subjective judgments are not coming from programming per se but rather a style of programming. Think: continental versus American styles of philosophy. Programming as we know it is arguably Western (structured, "precise" and all that hooplah). Programming itself isn't inherently Western, even if ARPANET was a US Grant, if you get my figures of speech, and grant me poetic license (which you probably won't do).
