Hello, world! I have been keeping interested in telecommunication since I was 13 when analog telephone with 2400 bps is good enough for communicating between home-use computers in my country, soon after the Apple SE released, if I was correct. A little later than that, that was around 90's, time was changing for the opening era for the ISDN line, that sped up to 115,200 bps at maximum with dual lines way-faster from analog 56,800 bps. I spend a lot to chat with local people for learning everything for living because there was no such thing as the Internet. We spent a lot of money for infrastructure for coming next-genaration. New services are always costly but always fascinating. What fascinates is communicating to the people living in the new world! Now I reached Citizendium, and I hope we enjoy this time of change.
