I'm wondering how much of that is bots.

Reddit is trying to build up to an IPO, so it's not far-fetched to think that Steve Huffman would have seen the exodus coming, and supplemented traffic with bots so the drop in engagement didn't seem so precipitous.

I think the thing that is going to suffer most is comment quality. Unfortunately (or for Huffman, fortunately), it's not really something that can be quantified.

I think we will see a slow decline until the platform is basically walking dead. It'll function, and maybe there will even be apparent engagement, but the quality will be nothing like it was before this whole debacle.
