I wonder what their analytics are on the amount of people who use old.reddit.com vs not. My guess is that once it hits a certain low threshold they'll decide to get rid of it. That will be a sad day.

I also fear they will pull what Twitter did and severely limit their API which will essentially kill third party apps and everyone will have to use their official apps.

Older users all use old.reddit, which isn't the audience they want to see growth with, but acknowledge that it's a lot of tech/niche sub mods that use it - so I suspect they'll leave it for a very long time.
