The future of blogs?

So everyone is talking about Web 2.0 - the new web. What is it? It is more interactive with blogs, podcasts, customized search engines, communication tools, sharing of photos, etc...

Do a search on Google and you will more or less around 12.5 million results...

I was looking at Yahoo's blog+ service and I have to admit it looks pretty amazing. Hmm, is notorious migrating to Yahoo?
