What if, when you went to a concert, there was a website where you could upload your photos, videos, even audio clips? Maybe do a little light blogging or at least commenting / message boarding?

Basically, it'd give you an online place to hang out and chat about the show after the event. Or for that matter, DURING the show if the mobile interface was good enough. I think it would be neat to see other perspectives, discuss ideas raised by the music, and maybe even make some buddies.

Would this be cool? Could you maybe build it pretty easily on top of existing community sites like Flickr, etc?

I like the idea of giving an off-line experience a footprint in the digital world. After all, online communication is a huge and rapidly growing slice of the pie already. On the other hand, what's wrong with just enjoying the damn concert!? Must everything be live-blogged?

I dunno. It's just an idea. Let me know what you think.
