Anybody know what's going on with this site?
They seem to have cut back the services on the site, there is no longer a ranking of the top and bottom correlations.
Is there anything similar to the original site on the net?
Not sure what happened to that site. Found a couple that might help - can't comment on quality, don't use them, but they look to offer similar features. Though neither have the fun 'tree' feature. HTH.
