I learned to type in Junior High School in the nineties, and it is extremely difficult to leave a single space after a period. Like that, it took a huge effort for me to break conditioning.
I was around for the leap from BBS systems to Fidonet; the bad old days when there were no such thing as graphics. I can absolutely sympathize with what's being said here, and for me, there are two primary reasons why I pine for the elder days. The systems then required some effort to gain access to which kept some of the signal to noise loss down (if you know the difference between CB radio and Ham radio, you know what I'm saying), and while commercialism's always been a part of these systems, more value was placed on content than advertising.
