Ask HN: Demo or Video?
I know dropbox had a lot of success by putting together a video of their idea. I created a demo page, do you think this is as effective? http://oim.ae/chatdemo
I can see where your app would be good, but I'm a developer and I have friends with English as a second language. If you had a video that showed someone catching up with a person they'd met on a holiday in another country or something similar then I think it'd put the problem you're solving in context better than the demo.
FWIW, I think it's neat. But for some reason, my brain acted like a deer in the headlights when I saw the two chat boxes side by side like that.
