These suggestions are hit and miss. Two-word names actually work well most of the time, and have the added bonus of making it easy to abbreviate if necessary. On the other hand, I mostly agree with the pronunciation guidelines, Pipl being an egregious example (none of them were fluent in English?). Moovit is OK though. However, it's strange that the author makes these pronunciation suggestions, when some of his own names violate them – Leaba is especially bizarre, Vayyar and Kodeos are pretty bad too. I suggest another rule: don't use vowel sequences that aren't commonly used in English, or pronounced differently in English than in Hebrew.
