Not only should they dump Microshaft, they should dump Real too. The streaming audio/video on their excellent news website could be done in mpeg or even the new ogg vorbis. Even Flash should be shelved, although there aren't any open alternatives to that yet.
After all, the *non-profit making* BBC are not motivated by any political ties, one of the reasons I much prefer them to, e.g. CNN, so why should they be linked to any commercial interests?
