these are quite some many questions ;) I can definitly answer the first one
for me, 1:22h is too long ;-D
And then, for the next questions, I guess I'm not the right audience.
(Though honestly, the length made me stop it after a minute :/
I definitly dont think it's useless! I definitly think there's an audience
for tutorial videos about Debian Edu, i just know -edu well & don't like
video tutorials cause I prefer to read stuff, so I stopped watching as I did. (:/)
