The Fridge wants to be your private social network:

With all of the privacy concerns around Facebook in the past few months, it was inevitable that new startups would rush in to fill the perceived need for private, tightly managed social networks. The Fridge is a cute, Y–Combinator–backed contender in that space. It offers up a simple service with a pretty clean interface and the basic functionality that made us like Facebook in the first place. Sure, there are no apps, but there’s a good space for conversation, and you can keep a lid on who can see your content.

In addition to posting messages, you can also upload photos, and The Fridge is clever enough to notice YouTube or Vimeo addresses in your messages, so they get embedded as players. It’s simple, and it works pretty well.

Of course, it’s certainly not without problems: the UI looks good, but it has some serious annoyances. In particular, the CSS buttons make the interface useless from the keyboard, which is a bit of a pain for curmudgeons such as myself. It also doesn’t gracefully fall back in the absence of Flash, so if you’re using a flash blocker, you’ll see some weirdness.

Overall, though, The Fridge looks like a good implementation of the inward–facing social network concept that seems to be all the rage (see my write–up on Micromobs earlier this year). If you’re looking for a private space to share Facebook-y sorts of content, take a peek in the The Fridge.
