I think there should be a law that requires women and/or couples to have a permit before having a child or children. Financial stability, mental heath issues , social stability, etc. should be checked before the permit is given.
There ought to be a way to have a gravatar selected per site.
There isn't and i don't think that will be one. It would be totally against the purpose of gravatar.com of allowing to use the sama avatar in many sites without have to set up each one of them. "One person, one avatar" would be the motto and not "One site, one avatar".
Right now, the html5 track specification has the attribute "default" that specifies which track should be on by default.
What would be better is my mind is to junk that attribute and instead have a user preference.
Someone who is deaf could set the preference to captions in their language, so that in a video with track information - first it would look for tracks with an kind attribute of captions and a srclang attribute of their native language, and automatically turn that track on. If such a track doesn't exist, then look for kind subtitles with their srclang and turn it on.
Someone who isn't deaf but wants subtitles could set their preferences to look in the opposite order.
