I’m an early adopter and I admit that freely. I opened a Grand Central account early its history, converted that to Google Voice when the time came, and have generally been impressed with the service. But I don’t use it much. I truly don’t feel that I can afford to use it for a variety for reasons.
The internet has created this crazy new paradigm of free services. The list is lengthy; Google apps, Twitter, Hotmail, Facebook, Blogger, Yahoo Pipes, Posterous, Gmail & WordPress.com are just a few. Free services are literally everywhere these days, like manna from heaven.
