You're quite right in what you say. However, I think it would make sense to have all the how-to videos relating to a particular model in one place. How you achieve this is another matter entirely, but the idea is thrown out there by myself for all to ponder. Basic topics that would be applicable to all models, such as "How to remove the platen", "How to remove the carriage", etc., could be set up and then people could be invited to add their how-to's to the right sections. I guess kinda like the same way wikipedia works. An encyclopedia of typewriter knowledge that anyone and everyone can add to.
