The latest buzz in e-business, unsurprisingly, is web 2.0 or the "read/write web." Almost everyone is familiar with at least some of the manifestations of web 2.0, even if it is only Facebook, or MySpace, or Flickr. But there is plenty more being tried out by a variety of businesses, from social networking, through podcasts and wikis, to blogs, mashups and RSS. Is this just a lot more media hype about the latest technology fashion, or is there something of real value here? Do you think web 2.0 can make a real contribution to e-business? And if so, what and how?
