I am becoming more sensitive all the time to the curatorial value of creating more signal and less noise.  The screencast below is a demonstration of that idea.  Take a river of noise like Twitter, get some initial flitering through someone else’s Twitter lists like Wesley Fryer’s and finally use nytlab’s Vellum as way to better visualize that list so as to scan and skim.

Of course, you will also want a way to gather together what you find and to broadcast what you discover in a discrete signal instead of just blather.  I use lots of tools for that, but that is another dozen screencasts.
