Chris Biscardi: On the top of what gear you need to stream? Basically, you don't need anything to click the go live button for the first time.
What Horacio is saying here is, "It would be amazing to help people understand that not having the 'proper gear' should not stop them to start streaming!"
He's absolutely right, because while I personally have been doing this for a few years at this point, I do a bunch of other things, like make Egghead video screencast of which this one is. I do other types of recording and video processing and things like that.
I have a consulting practice in which I like to have high quality video and audio for interacting with my clients, because it's all remote.
I have a very extreme setup. I have an SM7B right here. It's a fairly expensive, very nice mic. If you can afford it, I highly suggest it. Do you need it? No, especially not to start out.
The content of a stream is not around the kind of equipment that you have. The content of a stream is around who you are as a person, because people are coming to see you. You will have a bunch of people in chat who know nothing about the programming language or the framework or the design tool you're using or whatever you're working with or teaching.
You will have a bunch of people who have no idea, who are seeing it for the very first time. That's the content. The content is you being a person they enjoy spending time with more than it is the particular tool, or framework, or language that you're using.
In that vein, as long as you meet a very minimum bar...If I have a fan running, and I put it right next to this mic, what you're going to hear is that fan in the background a lot. As long as the background noise, like that, is not overwhelming you, you aren't recording in the middle of a Starbucks, then you're going to be fine.
Just get started. You don't need a mic. You don't need a camera. Just get started.
