Private Blogs

So far, I haven't told any of my friends that I have a blog. I don't really know why I haven't. I guess I want to keep it to myself. Also, they might say, " ________, you have a YouTube channel already! Why don't you just make more vlogs?" to which I would say, "It's easier to say things in a blog. Vlogs seem up-close and personal. I also have more fun typing something than filming a video of myself, editing the whole video, and then waiting for it to finally upload to YouTube. What is your opinion on vlogs versus blogs?
