io.net is just the most recent version of it. The groups.io lists I'm still on date into the previous century; some even into the 1980s. Some even back to Listserv. (personally I preferred Majordomo).Oddly enough, gropus.io launched in 2014. The precurser to web based forums was Usenet.
I don't recall much cross-over between Usenet and Listserv - they existed concurrently. Though some of the Usenet groups were echoed into Listserv - but it was typically one-way - as far as I remember. I suspect I have 30 years of VIA Rail posts hidden away in old email.
