I was never a heavy IRC user, but yeah back in the 00s, especially the earlier two-thirds, I had several different forums on my browser hotbar that Iād make the rounds through a couple of times each day.
Kind of miss that honestly, each forum was its own unique beast with an entirely different set of personalities without also being polarized. Contrast that to modern social networks which have a samey grey-paste quality unless one seeks out highly polarized services, which are often too caustic to spend time in without risking becoming similarly caustic yourself.
With all of their downsides, it's only huge social networks that actually brought the vast majority of people to the internet at all.
It was thriving for me, and I was barely a teenager at the time.
I would disagree with the timing here. I think the peak "everyone on one network" was Facebook in the early 2010's and since then the market has splintered to other social networks, sometimes along generational lines, others based on use case.
That's why social networks seem so magical early on, not only is everyone you like maybe on them, but there will be new people in the next week, month, or year that you'll like too. New things and new ideas are possible. But at some point, this turns sour. Eternal September describes that phenomenon, I think, but doesn't explain it well.
In some unfortunate networks, I think the latter can come even before the former (preempting it, making it impossible). You don't ever get the golden age.
Mastadon looks alot like this. Ignoring the politics, it looks alot like Voat did, and all the "we didn't learn the lessons of Voat" reddit alternatives that came after. It's almost as if you can't build a social network as a refugee tent city and make anything that anyone wants. Maybe that's the problem. In such a place where everyone is fleeing, there is nothing new there. It's all the same old people who were at the last place with you, there is nothing new about it.
The idea of a social network where almost all of your friend and family are on, is really something that started in the 2020'.
In many way, Mastodon is just the phpBB of the 2020', with the added benefit that you could connect to other phpBB instances.
And even though hosting your own phpBB instance or IRC/TeamSpeak/Mumble server kinda fell out of favor due to Reddit and Discord, they also kind of act in the same way. Sure you have one login to access all the community instead of having to have a separate account for each, but each community are their own bubble and can moderate however they like. It is not a "worlwide forum" like twitter or instagram.
