Nob Hill has been Nob Hill for a century. Your comment that we ought to find a new name for it is frankly rather stupid. I suppose Chelsea in New York ought to find a more original name as well.
Other than that nice comments, but you didn't see that much.
Next time you're in town, you really ought to explore the East side neighborhoods. Downtown Portland is probably the most lively downtime for an American city its size, but that's not really saying much given the competition.
Hawthorne is okay, but it peaked a long time ago. Most locals find it rather scraggly, though there are some cool things happening above 39th. I'd check out the Division and Clinton Street corridors, Lower East Burnside for great nightlife, East 28th Avenue, Mississippi Avenue, North Williams Avenue bike culture, and lower Stark Street.
