Ok, two things.
The first element loaded here on the train was stop soundtrack ... that made me bounce as I thought "My mobile tethering will choke on this" and "I don't have headphones hooked up".
* A lot of idle browsing come from idle time spent at coffee shops, libraries, and trains using low-power devices (e.g. netbooks, tablets, phones). If you want that to be your time then you have to play by those rules. Make sure your experience is acceptable for these scenarios.
* People don't expect playing audio on page-load. If you are trying to shock, ok. But if you are trying to get a message across, and people are around other people they will bounce from your site or have to quickly press mute...you're forcing your user to be really reactive here. Instead of trying to understand the content, they are doing damage control.
Think about your grandparents riding the subway reading the old-time newspaper or standing in line somewhere with the 25cent novel. Although our media today has changed, the purpose of the content consumption really hasn't. Make sure you captivate people in analogous ways.
Second, the domain made me think it was a reboot of "post-secret".
You can go with a goofy or an intriguing domain as long as you deliver something that matches the level of goof or intrigue. The delivery here is ok ... being on HN, I just expected more I guess.
