Blurbs seem fitting, but perhaps not the whole post. Actually, you may want to reference the true original post, where I found out about the petition to begin with (
link).
Vi anser att Sveriges Radio skall använda sig av det öppna och fria formatet OGG/Vorbis för sina sändingar på nätet istället för de slutna formaten RealMedia och Windows Media. Genom att använda OGG/Vorbis kommer alla kunna använda Sveriges Radios sändningar oavsett vilket operativsystem (windows, mac os, linux..) de valt att använda på sin dator.
"We reckon that Radio Sweden [should use] the open and free format Ogg Vorbis for their Internet broadcasts instead of the closed formats RealMedia and Windows Media. By using Ogg Vorbis, [it will be possible] for all to use Radio Sweden's broadcasts regardless what operating system they [want to??]* use."
Of course I leave it to your discretion.
* The original text used "de valt", which is a little different from what I wrote, but it doesn't make sense to me, even after adding 'ha', so I'll assume it's a typo.
