Just a heads up for non-portuguese speakers: brazilian portuguese and european portuguese can differ quite extremely in pronunciation. Then there's also african portuguese pronunciations, though to my ear those tend to be closer to the european. The article is written from a brazilian standpoint, so keep that in mind when comparing with your own experiences of the language.
Brazilians have a hard time understanding European Portuguese (I think that pronoun placement is a major factor other that the actual phonetics - they just don't expect certain phrases). And I've also heard from Portuguese that they find Brazilians easier to understand than some of their own compatriots, especially now that telenovelas have spread Brazilian vocabulary in Portugal.
In the late 80's & 90's Portugal started importing TV programs from Brazil. Since the 2000's this happens much less, but that has been replaced by a large number of Brazilian immigrants settling in Portugal.
As far as I can tell there are no equivalent influences going in the other direction, so Brazilians are rarely exposed to Portuguese pronunciation.
