Email app lets you 'leak' your secrets without owning up to them

"I drank all the coffee on purpose, so you'd have make a new batch." That's the first missive I received from Leak, an anonymous email service, which is -- so far -- not as barbed (or arguably, as interesting) as what Secret's social stream has offered up. However, the web-based Leak requires no sort of registration. You type in your pent-up resentment, shy confession and send it to away. There's no reply option, you're just sending an anonymous message from the internet ether, tagged with your relationship to the sender: friend, co-worker, family, friend of a friend or simply, most mysteriously, "someone."

When Leak's creator, Laurent Desserrey talked to Fast Company, he said he wanted to create a "really positive and exciting tool". And, due to its simplicity, it only took a weekend to build. While users can (and probably will) send negative leaks, Desserrey added that it's "really not what the product is about. It's about saying the truth you're ashamed to say." There's a well-intentioned 'Dos and Don'ts' guide right next to the send button: it outlines how you should be respectful, not spam, and not expose people's private information - the typical gentle rules of the internet. While lack of any login means it's more open than other services (there's no lack of anonymous email services), there's also inherent risk. Barring IP addresses, it could prove hard for the service to stop (or ban) anyone that doesn't follow the site's philosophies.
