Hey, I made this. I built it for myself, have been using it privately for the last six months, and opened it up publicly for friends this morning. (Which is why it has no credits/about page/nav/etc.)
It's an automated aggregator streaming tweets from around 1,000 Twitter accounts, extracting and normalizing the links, and then ordering them with a dead-simple ranking algorithm favoring URLs that resemble new projects/sites over articles/blog posts.
That's pretty much it, no idea how it ended up here.
