For me it was PCs in the 1980s and BBS (remember RBBS or Maximus when I embraced OS/2? (sorry another music que, ignore it! : [youtube.com
...] ) The ponies did run, of course, and here we are. :)
Back then I had two phone lines (above the home phone) and 4,000 subscribers for what amounted to pennies per day (okay, quite a few pennies!, limited to 1 hour in 24 and full access to FidoNet) and then Tim Berners-Lee introduced something called the web in 1989 which pitched my playground upside down.
I miss that early fun because it was fun where we invented all kinds of new stuff (ANSI graphics, Audio, Imaging, et al) and yet, where we are now is such a different---and yet---very comfortable and easy entrance place.
I was web before there was a web ... and became an early adopter and made that transition from BBS to Web between 1991-93, only to see AOL kill all that cottage industry off.
How to, from that point on, is where I am today. I'm still here, a bit more ruthless in some regards, but still loving the concept of shared info, hands across the water and all that other kumbaya. It's just fun!
