This. I ran ICQ on a machine with a single core 200 mhz processor and 32 MB (yes that’s an M) and it was fast with more features than Slack.

You just kinda had to be there. It was ever changing but snappy.
I like ICQ. I used it. But I really just don’t agree it had “more” features. It had _different_ features. And those features are just kinda wildly different because of how business and the internet had changed. I just really do not think it is a useful point to try and imply is a weakness of slack somehow.
