The article mentions GNU, and it took me a long time until I found out that English speakers pronounce it "noo", "new" or similar. My native language routinely has four consonants in a row, sometimes more, and gn is a perfectly common consonant sequence so it never occurred to me that the GNU project could be pronounced as anything but gnu. Turns out English speakers intuitively drop the initial g, or often have to insert a pretty obvious vowel guh-noo style.
