•  everything after "YT" in a paragraph links to YouTube
•  a link to YouTube is to a channel unless otherwise indicated
•  before I add a link, I check its content for at least ~30 seconds
•  I intend to check each link at least once per month
•  topics are ordered partially according to expected repeat link visits and content updates, which is why video topics are at the bottoms of pages, as a video is non-updating content
• a link to a YouTube channel is to use the channel's ID, not its handle, e.g. https://www.youtube.com/channel/UCBR8-60-B28hp2BmDPdntcQ/videos, not https://www.youtube.com/@YouTube/videos
