I personally like the new site. I think it is not hard to navigate, which is unusual for upgrades of sites (ie the new Facebook). I like the reviews a lot and plan on making a lot so that is definitely a plus. As of now, I cannot find any cons with this site but I haven't done a lot besides post and review ski resorts.
I think they're should be an option though, to also go to the old version for people who prefer that.
