It seems like an OK site. With these things polish is really key.

- Use fixed width layout

- align the sign in link the the right margin

- let people see submit links even if they aren't signed in. If they click on it, then sign them in.

- stock it with a lot more bits. Right now there are just 3!

- have more than one user. Get your friends in on the beta first.

- make it seem alive and constantly changing, so people come back.

- make the bits shareable on twitter / facebook, etc

- the iconography is sort of weird, I saw a pancake, an asparagus (?), and the logo looks like a green folded piece of paper with eyes and a bite out of it. If you don't know how to design (which is totally OK), then go for minimalism.
