I understand your point, but wouldn't doing what you suggest lead to the problem of maintaining two different code bases? This doesn't seem like a good idea at all.

I think a better approach would be to commit to their new design, and do some sort of A/B testing to hone down the new UI until it replaces the old one.

I don't think reddit will die because of the changes they propose. This is just silly. For starters, there are Google Chrome plugins to make reddit more Facebook feed-like.

I myself like the way reddit works right now and would not like it to change much. That said, Reddit the company has to move towards what will make them money. I don't have this data, but their user base might have changed in the past years. People that really enjoy infinite feeds, for example.

You don't have to A/B test whether a good product is better than a redesigned crappy one.
