Hi there Doug, Keith, folks, Speaking of broken mechanisms ... how many dots? arstechnica.com is OK co.uk is not OK ndots strikes me as a chocolate soldier in the fire used to warm the chocolate teapot that is search lists. At best these are context dependent (and keep IT support in business). At worst ... one day I WILL be arrested for tazering the bean counter (why is it always one of those?) who insists that "intranet" is a fine web server name useful anywhere. [I came damn close a few times with Yankee hotel reservations accessible only via 1-800 'phone numbers] Speaking of interoperability -- the comment "it works for everyone here" is not a good sign that the solution is interoperable. IMO, search lists and ndots are both abominations, and should not be given the oxygen of publicity. all the best, Lawrence On 24 Oct 2011, at 21:52, Doug Barton wrote: > On 10/24/2011 05:16, Keith Moore wrote: >> That's the point - search lists are not appropriate most of the time, and it's very hard for software to distinguish the cases where they are potentially appropriate from the cases when they're not, and it's not possible for software to do this in all cases. > > There's been something missing from this discussion, and I finally put > my finger on it.
