Are OP owner of this site?
Can you tell us some more details about how does it work?
Wow, sorry I'm epically late to reply. (Total noob error and forgot to check my messages).
Yes, I'm the website's creator. Happy to provide a bit of info.
Basically, the permalink for every post is a public bitcoin address where you can collect any tips/donations. The private key for this address is presented to you when you're previewing/buying your post. (You can also use one of your own bitcoin addresses for your post.)
You can sort the posts by most profitable, most expensive, most tipped, and most recent.
I also recently added hashtagging capability, and URLs are automatically linked.
The best way to see the site is to play around with it a bit -
