Any Web site that is not “under development” in perpetuity is doing itself and its visitors a disservice. When you “launch” a ship for an oceanic trip do you not make adjustments along the way to accommodate for changes that occur over time? You can’t swap ships midstream, but you can adjust the sails in a storm, take a hard left at the next glacier and by all means have a sit-down with a mutinous crew.
Point is: the launch is just day one of the ride. Stay awake.
