YouTube is the last social-ish platform I am still turning to these days. I need to cut back on some of the videos I am watching, but this short one on ripping gaffer tape is pretty good. I had fallen into a motion lighting/gaffer YouTube hole over a year ago. This morning I came across this video, it is worth a couple minutes of your time.
As a bonus, here is a good video about grip clips. It is also worth a view.
