I assume so. Youtube has some software (of which I know little) that enables you to upload homemade video that you've shot using your webcam.
If you're going to start,you have to start somewhere. At least, that is what I keep telling myself in my business life. (As opposed to real life, dance life, work life or internet life lol)
My business is online and could benefit tremendously if I podcast and/or vlog. I keep holding myself back by saying that I need expensive equipment. Truth is that lots of stuff on youtube is very, very basic. Anybody can do it and most people get better with time.
