This is the dumbest move I've seen in a long while.
Sure, SnapNames and NameJet shared (some) data, but no domain investor in their right mind used SN, as their Search Engine is crap (with few selection options) and their Domain Lists are a joke. NJ was THE place to go for domainers because the site actually worked and provided quick and relevant domain information.
Now it's just one big smelly disfunctional mess that everyone seems to be angry about. Did they even think about consulting the domain community (i.e. their customer base) before pulling something this drastic?
WTH were they even thinking, as the "lost features" are some pretty freaking big & important ones, and now these look gone forever. Did they actually believe (in some drug-fueled haze) that the features and options on SN duplicated those on NJ? Who's running the show over there, Curious George?
I can almost guarantee you, that with the significant loss of features and functionality, NJ/SN are going to see a noticeable drop in revenue. Just try searching to anything at NJ and see what kind of results (and a lack of filters) are available. Anytime I try I just get a big pile of garbage.
