Gerry McGovern opens a recent article with an incredibly clear statement about the current environment for KM:

We are in an era of knowledge abundance. Traditional management theory focuses on knowledge scarcity. We need new management strategies to deal with so much communication and so much knowledge.

This is why blogging, RSS, newsreaders, wikis and similar technologies are coming to the fore now. They are effective tools for communicating in an environment of abundance. Love that quote! This will definitely be making its way into my presentations (with attribution, of course).
