Have you ever heard the line: "How do you have time to make these videos?"
That translates to- "I'm not interested in your humor. Please take me off your distribution list." This also goes for "you're crazy," "you are so weird," or "your kids are going to need therapy."
The highest compliment for your online video is, contrary to popular believe, not "LOL" or "Funny as Shit!" The best way to support someone else's video is to comment on one specific moment you thought was funny. This is nice for two reasons: 1) It shows you actually watched it, 2) It's constructive so you know what created impact. The second best response is constructive feedback- I love when someone tells me something was too long or missing a good ending. That helps too.
