i do not understand (at all), since we all -massively increasingly- suffer/drown from/in information overdose, that people publish uncut lectures (in fact - seen as act, it is nothing but: unreflected publishing).
lectures usually do have a title (&concerne) - one clicks it, to consume/pickup information according to titel & explanatory subtext. then being confronted with students self-introductions and details about possible attendance (of students) of possible courses & classes .. i am sorry but i perceive this as a complete irresponsible acquaintance in regard to the (very) precious time of people and therefor i conclude, that the person who contributed this video material is seemingly not a person who should (at all) be involved in knowledge management. knowledge workers big concern&task today, has definately to be: reduction.
no - i am not talking about zensorship, but exclusion of irrelevant information, that has nothing to do with the semantic contained in the titel.

That was me wearing a wig.
