One of the biggest obstacles for Open Media is the lack of it not only out there but even in your own computer. This needs to change, and YOU can help.
You already have some content in your computer, be it music, podcasts, videos, office documents, etc. All you have to do is convert it to a free format and (if it's legal for you to do it) share it with other people.
This is, without any doubt, the most important step you can take to promote Open Media. Do it. Now.
Sing songs of praise to Operation Transcode. Help your friends (who don't think you're crazy) to do the same thing. Help make the world a better place. And next time you see that stray dog by the road, give him a pat in the head.
