They've actually done a masterful job of finding this balance. I've been on reddit for 15 years and would have quit if they didn't leave the old interface available.

On the same day that old.reddit.com stops working I'll leave.

The mobile version is literally unusable. Half the subs show an error and you can't load most comments.

I think it's because there haven't been any interesting alternatives. I know if I ever see one I'll probably switch in a femtosecond.

Not _yet_, the same was said about Digg once.

I honestly thought Reddit would die when they introduced Reddit awards, it seemed like such an obvious cash grab. You can't underestimate the amount of community momentum that the site has though.
