I'm not old enough to "remember" the days of free love in the 70s, but I doubt there was very little difference to what happened in the clubs during the late 80s and 90s. Given the club scene (of any era) vs access provided by the internet, all I have to say is "thank you Al Gore"
Hell, I wished we had the information on the net in the early 90s like we do today. I remember my early days of hobbying consisted of newspaper ads in the sports section and the yellow pages. Nowadays with the internet, I can find a provider of my choice, interact days in advance, and essentially have a date like meeting. Isn't the internet great?
