Boing Boing: A Directory of Wonderful Things. This is a neat geek site for interesting gadgets and a multiuser site. Here's a note from Clay Shirky about VoIP. I have to give it a try!
I have been testing Vonage's VoIP service, and it comes close to the critical mix of simple, useful, and cheap. The key difference between Vonage and previous "You computer is your phone!" models is that now your phone can be your phone, thanks to Cisco's Analog Telephone Adapter, a box that takes a phone cable in the front and ethernet in the back and does pretty much exactly what you would expect a box that takes phone cable in the front and ethernet in the back would do.
