My nostalgia for the ancien internet is deep and abiding, but it does not extend to actually wanting to use Usenet again. Usenet was never a good solution, it was just the only solution for a long time. So, to the extent that the proposition is for something that is Usenet-like, my vote is no. If you're saying "should there be a better, decentralized Reddit that is not garbage like Usenet" the answer flips instantaneously to yes!
I find that this nostagia is mostly to who was on that internet, rather than tech at the time.
By far much less monetization or ads so far less SEO spam (and so less need for moderation and/or spam filtering), minority of population so not much political campaigning aside from personal conversations about the topic, more technical people etc.
