Wikis

The most interesting thing to me about wikis is that they provide a collaborative, non-hierarchical method for building a web site. They're the most extreme example of a web application that I can think of that does this. One hopes that the collaborative, egalitarian spirit that underlies their design would permeate other avenues of decision-making - at least in those situations where it's appropriate. But on this point I'm probably engaging in another idealistic fancy.

As for what types of library applications might work well with a wiki, these have already been succinctly delineated in the post, Using Wikis to Create Online Communities, an article linked to the Learning 2.0 site on wikis. I'm afraid I can't yet think of any other suggestions beyond what the author mentions. Save it to say that all the examples she mentions - using wikis as subject guides, annotations to a library's catalog, as an online hub for community information, and for collaborative group projects between librarians sound appropriate.
