Oral and transition cultures tend to transmit information that is more concrete (less or not abstract), accretive, formulaic, redundant, conservative, situational, additive. They do not have external sources of information, except in rare situations, to consult. If they do, they are less trusting of written materials and would rather talk to people about whatever it is that they want to know, because they know who is trustworthy and who is not, and because they can ask questions.
Analogies to pod casts and giving talks at conferences have absolutely nothing to do with oral culture or oral transmission in a oral culture. We are today totally operating from a literate mentality and consciousness which allows us to write things down, to remember them, to store them, to refer to them, to develop them, to memorize them verbatim, and so on. We trust external sources, the written word, things we can consult, and even in court when we have oral witnesses, we are all about documentary evidence and challenging the witnesses against written records of what happened or what they might have said on another occasion.
If you want to understand oral culture, read Walter Ong - everything or anything he wrote.
