Nothing is more depressing to me than watching a bunch of vlogs about politics. DC is so overrun by media, that I don't think Vloggercon will garner much press if held there.
Now if you want to be noticed, then the obvious place is New Orleans, LA. Imagine flooding the vlogosphere with scenes/stories about the rebuilding effort there post Katrina.... Plus, there's a lot of interesting things to do/see in New Orleans. Imagine discovering the French Quarter, or eating some of the best food in the country, or seeing a swamp or alligator for the first time! The culture is so unique in Southern Louisiana, you might think you are in a foreign country. Once you've seen a bunch of monuments and museums in DC, what else is there? How about something else, something real that is more humanizing? How about vlogging real people in a real situation that demands the nation's attention? I believe traditional media will pick up on Vloggercon if held in New Orleans. Chuck
