I believe the right URL had a prefixed www. (During some downtime, but not this one apparently, http://wrongtomorrow.com didn't work but http://www.wrongtomorrow.com did.)

Back in July, Maciej told me

> It's not abandoned, but I had to take it down since a sister site on that server was getting high traffic, and needed the resources.

I began copying over predictions from Wrong Tomorrow and Long Bets to http://predictionbook.com/ and I found that a bunch of Wrong Tomorrow predictions were corrupted/unavailable, and told Maciej about them; no reply. So I think it's safe to say that Wrong Tomorrow has been pretty much abandoned.
