I am adopting a policy of usually deleting all links to podcasts and
videos more than 5 minutes long that are posted in response to
Facebook threads that I start, especially if the speaker in the
video is someone who I have never heard of.
Links to articles are much better, because I can skim ahead in the
article and see where it's going. I can read many times faster
than people in podcasts and videos talk, and if they start
blathering about something that sounds irrelevant to me, I
can skim over it and see if they ever recover to the topic being
discussed. Podcasts and videos are jail sentences where you
sit and have to listen to lengthy introductions and then the person
slowly goes on and on and on.
If you learned something from a podcast or video that really does
shed much light on a topic, you should be able to
articulate it on the thread.
Also, it is easy to cut and paste a quote from an article into the
conversation, while it is very difficult to do anything similar with
a video or podcast.
My experience with references and links and especially book
references when people refer them to me in an argument is that, 85%
of the time, they either fail to back up what the person is saying,
or are posted by someone who was missing the point of the debate
anyway. If they post a link to an article, then I can quickly
size it up and see if it has any relevance whatsoever to the
conversation. You can't do that with podcasts and videos.
