The Case Against OGG
Steven's first entry of The Catch-22 of Open Format Adoption is on music formats and he does a great job of explaining how I feel about OGG format audio as well. It's a great format, but it's a pain in the neck to support a format most people can't play or use.
It would be nice if this MP3 license fee business would become public knowledge so everyone would understand how much nicer it would be if we used an open format. But that seems to be a ways off.
