Artists, and other content producers need, Vorbis to avoid paying percentages of their revenue to some technology company in Germany. Most of these people are also interested in having the best sounding quality product that they can get. People won't choose Vorbis or MP3 files simply for the sake of technology. People want music from artists they appreciate, or shows on topics they like, and they want the music to be available, transferable and easy to manipulate. If there is content being produced in Vorbis and applications all support Vorbis, the user probably won't even notice.
Ease of use is achieved with transparency.
How You Can Help Just like any open-source project, Vorbis reaches its full potential only with the help of the community. Programmers, audiophiles, musicians and evangelists are all needed. Encode some music with Vorbis, listen to Vorbis files and let us know if you hear anything that isn't in the original. Artifacts, once someone identifies them, are usually easily fixed. Not only will the audience for Vorbis grow, but users will appreciate the functionality that Vorbis offers.
