Okay, cool. You also have to consider that most of these dudes write for specific audiences, and the papers you read and the TV programmes you watch, cater to a specific audience.
For example, City Press or SABC doccies, all have a certain group in mind and their journos might not be all that clued up on the person they are interviewing. Their main aim is to introduce this person to the audience and get the word out that he exists, so they stick to the basics and then give a little background knowledge just to clue you in.
Unfortunately, if you want more in-depth reporting, you may have to go to speciality shows and mags to get the gritty info.
