Someone linked me to a Usenet discussion on November 9th, 1989, as a bunch of college students in the US and Germany discussed the implications of the fall of the Berlin Wall. It really drove home to me that people have been talking politics on the Internet as long as there's been an Internet.
Do you still have that link, by any chance?
This might be it.
That is indeed it, though I seem to have misremembered the contents a bit over the years: I recalled at least one person arguing for dragging Austria back into the new united Germany, but apparently that didn't happen.
