I share my videos with everybody. Well, I don't necessarily go up to family members and tell them to watch my stuff, more like post them on my personal Facebook where they have access to them if they want. I'm not all too concerned about it. If they don't like what I post, they don't have to watch it.
When I started Youtube I made videos with my little brother and cousin, so they obviously know about my channel and subscribed with their accounts. Plus my older brother watches whenever I upload. I haven't uploaded anything in a while, we'll see what happens on the 9th, but I don't think anyone else in my family really watches or knows about it. I don't go out of my way to keep it from them but it just never comes up in convos.
My videos are about mostly about vacations, so instead of showing them photos they can watch a +- 5 minute video of it. Sometimes my parents for example are even looking forward to it The other ones are about events like concerts / festivals I've been to and I'm going to make some more video of my dog, so it's no big deal.
But I guess I'd feel awkward when they would see me talking about something in front of the camera.
