Congratulations Debian! I learned with Debian a lot of Linux. My first distro was Ubuntu 10.04, then I tried Linux Mint, and then I met Debian. I always sticked with the testing branch. Have a lot of issues, but it helped me learn a lot of Linux.
The last couple of years I've been using Deepin & Ubuntu, which I have liked it very much too. Maybe I will switch someday again to Debian.
