Flavor Sofa is a new service which allows users of VoIP or Instant Messaging to charge for calls. Not a lot of sellers at the moment but to be fair it has just launched. On the other hand paying someone $4.99 per minute to learn about SMS is probably not for the average punter. And I am not sure you could learn to fly a helicopter over Skype, even at $1.99 per minute. They also probably went a bit overboard with the spam solution angle in the press release when they claim: "...because callers have to pay, the system is a very effective spam blocker. If you charge $10 to answer calls to your Skype address, you'll only hear from callers who are reasonably serious." Exactly! You won't get calls at all from friend or foe.
Then again there are sillier charges in telecoms such as data roaming. 10 pounds per megabyte! No wonder many of the mobile carriers are not thrilled about handsets with wifi.
