My first experience online was back in the summer of 1992, when I got my first modem. I hooked up with Compuserve. Back in the days when you had to pay by the hour instead of a flat monthly rate. Needless to say that only lasted a couple of months and it would another five years before I went online again. This time with AOL.
I'm surprised that some people think that facebook was the first internet experience for most people. I think it was AOL etc. The platform was pretty self explanatory. It was a time when was more civility online, mainly because it wasn't as easy to access the internet at the time.
