I post a lot of videos on YouTube. In fact, I have two YouTube "channels" that I run and a couple others that I started for other people. On one of my own channels, I post items about arts and events in my local community, sort of "hyper-local" items of interest. When there's a fire or flood in my neighborhood, I pull out a camera and shoot it. Once uploaded to YouTube, I send the link to a couple of local news blogs and these videos sometimes get quite a few looks.
For example, one video I did was on a training fire for the county fire department. The fire department deliberately burned a house in my neighborhood (donated by the owner, of course), and this made for colorful news coverage. That video has nearly 1,400 views, almost all from local news blogs. Another time, within sight distance of the training house fire, I pulled out my cell phone and recorded a car driving into a flooded street. In just a few seconds, the car was floating. That video has more than 1,500 views, most from local news blogs.
Those may not sound like a lot of views, but anyone on YouTube will tell you that getting more than a few dozen views on a video is unusual... getting more than 1,000 views is a resounding success for a hyper-local news event. It shows that there are lots of locals interested in news events and can't get their fill from nearby TV stations, which cover more regional news and typically not events of interest to a relatively minor neighborhood.
So if you see news, pull out a camera or cell phone and start recording. Narrate what you're seeing. If necessary, do a little editing to touch it up, and load it to YouTube. Let a local news blog know and you will become a journalist. People are hungry for this kind of news, so you'll make friends doing it.
