I've never been especially interested in watching speedruns of videogames, but I found Summoning Salt's YouTube channel a couple months ago and have really enjoyed watching the videos related to games I'm familiar with.

It's very interesting to see some of the simple tricks to speed up your time, as well as the extreme lengths some people go to in order to shave off every last (fraction of a) second possible.
