On the gaming.se site they have the ability to embed YouTube videos in both their questions and their answers.
I think that embedding video, especially for questions which require detailed, complex answers, like proper maintenance steps for suspension forks for example, could benefit here as well.
I'm sure that not every question here requires a video response, but if the facility exists on Stack Exchange, why not use it here, too?
This is a gaming.se question which demonstrates the ability.
Edit:
The question on how suspension lockouts work brought this up for me. Explaining that without visual aids well is difficult, and creating your own visual aids is hugely time consuming, which is a barrier to good answers there.
I do think that @NeilFinn has a point about linked content vanishing, but that should be something we can deal with, since this is already live on a few other sites.
It also is something that applies to any linked content, not just embeds, and embedded video which isn't copyrighted rarely gets pulled from YouTube.
What do you think?
Edit#2:
I asked the question on Meta.SO, but it refers me back here, to our Meta site as the path to get it enabled. So how do I proceed with this request?
