Well, that was an interesting year. Was it really the year of Web 2.0 and 'community generated content'? (as suggested by the BBC) Or, as I would suggest, it was more a case of the media finally figuring out what has always made the Internet more interesting than just the news sites... the long tail that's been there ever since people have had their own spaces on bulletin boards, their homepages, or news group communities.
YouTube, facebook, MySpace and the rest are simply higher bandwidth, better publicised, better financed and more widely used versions of the things the Internet has thrived on since it's inception in the early seventies.
After 30 years, it's about time the conventional media finally figured this out, but you know journalists. As soon as you read a news report about something you actually know about (through expertise or personal involvement), you see countless glaring errors. Makes you wonder about the rest of the news they report!
