One of my regular reads comes out with this handy annual trend-watching tool. Most of the trends are connected to the net and imply a great deal of social networking software. If you're a manager you really need to be asking yourself, what am I doing today to participate in these trends that are already unfolding?
Open source, like the blogosphere, is a grassroots (bottom up) movement. Try not to let the grassroots lull you into believing that it is about one or two people with an idea or cause. Today's grassroots ideas on the net become viral in days, scaling in volunteers (Seth, will you help us) to what would make any organization or marketeer cry for mercy or celebrate in the streets. But, that's not happening in most business organizations. Too bad.
