At this point I will be very surprised if old.reddit.com survives another year. I hope it ultimately kills reddit, but they'll inexplicably be worth more for this I'm sure.
They will be worth more temporarily ... I used to be a heavy contributor 10+ years back. Scaled it back drastically to daily browsing to catch local news and online memes (only on old.reddit.com). By trying to force me to login to even use old.reddit.com, they lost me completely as a consumer too. (Interestingly, as I cut down on Reddit completely, I also somehow started using HN less too - I often used to alternate between both when I was bored).
