Hmm, I'm genuinely curious: why? I tend to heavily dislike anything infinite-scrolling...
1) You immediately get to see the date range of the thread. 2) You can instantly navigate to any date or position in that range. 3) Thus, it's not really infinite scrolling. At all. The only similarity is lazy loading, for long threads. 4) On mobile, you also get to preview the comments before actually jumping to it.

Yes, it’s awful.

Oh lord. 40 comments? That’s a single page of traditional forums.
How does it work when you have 1e4? 1e5? 1e6? And yes I do mean threads of a million comments.
The mobile preview is probably a nice touch, though.
