So - what do you need to consider to get onto that platform? As far as a monetary investment, a really capable little video camera can easily be had for $150-200. The current digital video recorders offer much greater transfer speeds than the old tape models, and can even provide high definition without getting too expensive. One accessory you'll really want is a tripod, and while a full height one can come in real handy, at least get a little desk top model to keep the camera steady and aligned.
Then, unless you want to get into sophisticated production, you probably already have free editing software on your PC (Moviemaker) or Mac (imovie) which will even allow you to add text to your video to display your name, title or business url. Once the movie's loaded into and completed in your computer, it's easy to upload to the web.
After you've gotten your gear together, you then get to work on the two big things you bring to the show - yourself and content. And when I say "yourself", I mean your real self, because we are talking about a social medium where you want people to perceive you as genuine, relatable and trustworthy. In short, unless you actually wear a suit when you're relaxed, you probably don't want to dress up & "play professional" to make a video presentation.
Also connected to presenting yourself, in addition to your clothing, is your setting. Sure, a comfortable place in your home or home office (as long as it doesn't look a mess) is a natural choice, but a place "in nature" can also help provide comfort to your viewer. I've seen and actually used the car as an everyday site for videos. Just be careful with your driving!
Then - present content on which you're knowledgeable which will be of interest and value to your audience. If you can make it entertaining, all the better - if your video is fun, it may get spread virally! Go for it - you can be in the movies.
