Thought you'd like to know. Good luck.
To answer your question: it's a place to come for an infinite stream of stuff to read after you've exhausted your usual haunts and are still bored. When you vote up a story it's more likely to show you stuff from that site. When you vote down it's less likely. Basically a feedreader for people who don't understand feedreaders. There's smarts to show the full text, that works most of the time (try clicking the green arrow at the bottom of some stories). When you get to the bottom of the page it'll autoload more stories.
There isn't that much more to see if you register. We repeat users don't like the scrolling so it shows just one story at a time. There's keyboard shortcuts. That's about it. I pruned everything that didn't work. Thanks for checking it out.
