If it's just about keeping a link to a handful of content creators, and you aren't a multiple-hours-per-day yt addict, there is already a nice solution for that, which universally works for all web resources and is well supported by all browsers under the sun.

I'm sure thay's not ideal (e.g. not for Google trying to understand you better) for the addicts, but for the other ones, this can be the perfect solution.
