They both make perfect sense when one has a solid grasp of English comprehension. They are both totally generic and can be applied to anything that needs to be edited within the 'cloud', group editing comes to mind straight up, teams working on projects and whatnot. Cloud themed domains sell, I have CloudCrucible.com myself but I'm not trying to sell it.
Editor.Cloud is an application waiting to happen with unlimited variations and potential. $250 to $1000
Edit.Cloud should probably point to Editor.Cloud. $50 to $250
