Cruise through Netcaster's list of channels and see what you think. The right channels, for the right people, make sense. If you find a channel that's a good match with what you do, by all means tune in once in a while. But if you're subscribed to more than two or three channels, something's wrong. I suppose I can see the allure, but no thanks.
Some channels simply make no sense at all.
You may ship a dozen packages with FedEx daily. You may hold stock in that company, you may even work there. None of these are good enough reasons to subscribe to the FedEx channel. Shipment tracking on the Net is a wonderful tool, but only obsessive-compulsives would stoop to using push technology to track every step that their packages take. Of course not.
