Going back 17 years when I first really got into domaining the reports were all about 'sales', but there would be the occasional story pop up on DNJournal and other places of a domain name being 'leased'. To me it seemed that this is surely the way the industry would be heading, no not for the most part but that a substantial section of the industry would go along this path, after all with brick and mortar properties the leasing of premises is seen as a legitimate part of that industry, indeed businesses lease vehicles, machinery, etc., so why wouldn't the same apply to domains? So now jump forward 17 years and the domain industry still by and large does not seem to have gone down this route. Yes there are well known domainers who enter into such arrangements, perhaps the best known of course is Rick Schwartz who all but champions such deals, but although there have over the years been numerous attempts by individuals to develop this market niche generally it still does not seem to be an accepted norm within the industry. (Indeed here on NP there is not even a section dedicated to 'names for leasing'.) This lack of development of a market niche is my biggest surprise over the last two decades so I would be interested in finding out what other domainers 'surprises' are and specifically things that have NOT occurred that you expected would have occurred.
