All of the Reddit replacements are trying to replicate Reddit but without what makes Reddit actually the great: the mountain of archived content from over the years.

This premise, I feel is the wrong way to look at it. What you think what's makes Reddit great and what made reddit great to me are totally different. What each user wants or expects from a reddit alternative is something that ISN'T Reddit. If I wanted Reddit, I'd go back to Reddit.

From your post, I don't think you were really into internet forums. I was a part of several dozens forums, with tons of overlapping and also different discussions. I was sad when many of them slowly died as Reddit dominated niche communities. The current expression of the community-based fediverse such as Lemmy and Kbin are a return to form that I deeply missed. In the old days you could have an art subforum and the vibe of each art subforum was totally different, but shared the general themes of certain styles of art.

I think the "fragmentation" of the current fediverse is great, its no longer one massive hivemind of a single dominate discussion points. I think in the long term, many of these communities will grow and change to suit their respective audience and some will fall out of favor and that's okay.

I personally do NOT want a single technology community. It becomes boring and samey really fast as the same opinions are reiterated over and over. Focused unique communities will come around that will be my peak of this amazing system.
