Someone said that a single photo is as effective as a short video. I
don't agree.

Guess I'm trying to encourage on topic video posting.

There is some very good stuff on Youtube, there is some really bad
stuff. If you find something good, please post a link. Finding the good
stuff is the challenge.

It is easy to make short videos and post them.

We all have cameras that make quick time videos. Try it. You may like it.
