Actually, I have been using Debian (off and on), since the 1990's. My first real GNU/Linux distribution was Debian 2.0 - "Hamm"!
"I wish I could quit you."
- from the movie, Brokeback Mountain
I have dabbled a little with testing before, but mostly stayed with stable, when I was using Debian. Always hated to have to choose between an up to date system or security and stability. There always seemed to be too big a gap in-between the two choices.
BTW, thanks for all the friendly, knowledgeable advice and input. That's one of Debian's best features. It's a refreshing change from some other F/LOSS communities, which shall not be named. Some are friendly, some are smart, but that rarely goes together. (And some are neither!)
