As for the Topics of the Day...
I can't remember the name of the first Word Processing program I used, but it was a WordPerfect knock-off - all those formatting tags. And since this was in the days before WYSIWYG (What You See Is What You Get) and HTML, I never really knew how it was going to look until I printed it out. So, I usually ended up printing out whatever I needed a couple of times until I got it right. -Oh, and, of course, there was that "wonderful" dot matrix printer with the continuous feed paper...
However, the one program I remember using a lot - pre-Word - was AmiPro. It was WYSIWYG and I used it until it was no longer being updated/manufactured. I think it eventually got bought by another software manufacturer.
...And I also used one of those TANG consoles when I was working as a clerk at Coast Guard HQ during my college summers.
And as for video games...
I did have Pong. And, yes, there were those times when my brothers and I would set it up so the ball just kept going back and forth and back and forth and back and forth... Sometimes we would leave it on like that overnight.

Otherwise, I remember an Atari system - Asteroids and QBert.
