My buzzword of the week: 'Slivercasting': short digital video content that is easily and cheaply developed and disseminated to a niche audience, often on a regualr basis. Think video podcasts, videoblogs, citizen journalism. Cameras, editing suites, storage space have all gotten cheap and easy to use. Popular vidoeblogs are beginning to generate advertising revenue, given their large audiences. The grumpy old media guard have taken notice.

In terms of libraries, another content stream with deep archival issues. In ten years we can read about a popular slivercast (perhaps in a newspaper archive) but chances are we'll never be able to locate a copy to view.
