Collaboration with Lists and Search

In CWorld:  Short view on the continued evolution of collaboration software.  Its acceptance within the enterprise.   As they say there,  this started with a very simple idea, the to-do list.    Most collaboration that exists is based on that humble idea.   Yet another way to look at collaboration is via a common task.  One that needs to be more collaborative and focused.  And what is done more often than search?  See Zakta's approach to this, which I have now reviewed a number of times.   Worth examining.
