Heavy Metal Parking Lot as the prelude to the modern grassroots video movement

Thanks to a post by Reverend Groom, Heavy Metal Parking Lot was once again forced into my conscious active mind. Youtube has made a film like this obsolete, since this generation is now chronicling itself on youtube, and a camera pointed at a youth subculture is no longer a novelty.

This film is a great milestone in the evolution of grassroots video from the chemical (film) to the analog (video tape) to the digital. Just the fact that is such a cult classic says something about the time it was made. Footage like this was scarce. The genius was in pointing the camera. The movie's bootleg distribution of a copy of a copy of VHS tapes functions as an analog precursor to the large scale democratizing of video enabled by the internet.

Question: has youtube made people more savvy about being in front of a camera so that they are better are shaping their presence, and as such, would not act quite as dopey on film as the denizens of the heavy metal parking lot?

Overthinking this little filmic gem is kind of making me feel dirty.
