Professor Cheese recently brought up the Homestuck episode on Tumblr, and as it turns out one of the old hosts chimed in.
This is what Kenyatta had to say about the issue:
Qualifier: all I do nowadays is lurk in the KYM forums and db so I know nothing about why KYM episodes continue to be shot 3000 miles away from the staff. There may be a good reason for this. However…
In olden times, every KYMer who got on camera was also a part of the KYM community. They were co-authors on their scripts and did at least some of the research on the source entries themselves. It was the only way to make sure that the person talking about the thing actually knew what the thing was actually about.
Even with that setup, we still had weekly All Staff meetings where we discussed and debated and fact checked every script being researched. And everyone who worked on the script was also present during the shoot and could raise a flag if something didn’t look or sound or feel legit.
And, of course, before a script was even written, all of the facts were vetted by the authors, editors, and contributors who wrote the articles themselves.
This meant that our margin of error on episodes was near zero(ish).
The handful of times we ever got our facts wrong in an episode was usually because I alone would accidentally something or other during a last minute rewrite. In those few times, if I had just left it to the group, everything would have been okay.
