Well, it would appear someone was listening, the "new" version of the site got rolled back to the old version.
Hopefully the next experiment will work out better.
I think they split it up while they continue to fine tune it.
http://www.nicehash.com - old
http://new.nicehash.com - new
I still prefer the old one
Having the new site up for testing and feedback on a different URL makes sense.
(edit) except they're now forwarding the "www" address to the "new" address, which does NOT make sense and is now ticking me off again.
