For Panoramio (and GE/GMaps), my idea has always been "what would it look like if someone were going there to visit"; and I've tried to do that with "photographs", but there certainly are "snapshots" in my gallery (and an occasional "artsy" shot; oh well); but all with appropriate 'Titles'. I've also tried to keep my 'Tags' as succinct as possible, so other similar shots can be easily viewed. (And, of course the Tag "Not Selected for GoogleEarth" is always an option.)
My 'Profile' shot is of riding on the platform between railcars on the White Pass & Yukon Railroad; I grew up in a railroad town and so trains have always held an allure; this ride was a superbly enjoyable time.
Thanks for visiting and I hope you found interesting and enjoyable shots.
