I do. Reddit was this awesome super/meta community of darn near any specific, niche, rare subject you could think of - and that thing would have a community of its own in a subreddit.
The amount of utility, the breadth of concentrated access to subject matter experience on anything, was utterly unmatched anywhere else.
This is, in my view, the dying of that resource, that super-community, and there isn't going to be anything that can replace it quickly. That will hurt in the short and medium term.
On the other side of things, it will lead to a diaspora of sorts, with other communities such as this one (kbin), various instances of the Fediverse, Tildes and others seeing a significant period of growth, and, probably, an infusion of resources to speed and improve development for the better.
It sucks right now, but I do have hopes for what will come from the ashes.
I cannot wait, and I hope to everything that the viable replacement turns out to be this decentralized network. For all the same reasons you mentioned. Reddit was my Google, because Google search has been trash for years now.
This video about Google really sums it up well and talks about Reddits role in all of it.
