Conferences on video
Conferences are a more or less efficient way to deploy new information, the more people take part in a conference the better information is spread.
This is the problem. Very often only very specific details score off for specialists.
The retrieval of those details has to take in account that specialists would have to take part in all conference panels to not miss this detail, or they need hints to where to find these details in video archives.
If video archives do not show the possibility to index the videos and then personalize the indexes, it as a repeatedly time-consuming task to communicate solutions proposed on live events.
