What is non-linear search

Ian Delaney has a great description.

In brief:

Non-linear search is one of the bounties of the web 2.0 approach that has been relatively unheralded. Instead of finding information a la Google, social search is about finding knowledge. The idea is how do you connect with the information you need in a context that’s knitted together by people and by human expertise, rather than the linear way we do it now, which is to type a search term into a box.

PS another reason for PR people to use tags when providing social media services.
