If it's at all possible. I just find it kind of annoying to have to scroll through super long posts just to get to the comments. Review threads for newly released games in some of the gaming communities are what prompted this idea lol.
Edit: what the hell is going on with that account that keeps spamming nonsense?
I don't know if it's a solution you'd like, but there is a bottom nav bar for comments. That's what I do for those really long posts. If you gimme a sec, I can find the setting link for you.
