I totally agree with the point of Reading Vietnamese is the easiest skill of all skills.

Because when i read Vietnamese i try to speak out loud. And when i listen to Vietnamese music or programs, i try to vizualize, picture the words in my head. In my opinion that make Reading easy compare to speak, but also in my opinion an important skill. 

It definitely helps Westerners that we can recognize the roman alphabet, it makes it easier to pretend we can read... But getting it perfectly right is another thing entirely haha. So yes, maybe reading badly Vietnamese is easier, but mastering it will need tonal practice and the sounds that aren't present in our language... such as dh or đ or gi. But a bigger challenge should be a bigger motivation as well :)

@Phil Yep, I can't agree with you more :)

Yes, Vietnamese is a tonal language and of course you have to be careful when you say something. Because different tone making a different meaning

Vietnamese is a tonal language, right?  It probably doesn't hurt that the melody likely hides a lot of the learners' inaccurate tones. (Although glottalization and other special phonation would still be an issue.)
