A few weeks ago we hinted at some of the personalization tools that Los Angeles based startup Gravity would be unveiling. Today they&'re launching Twinterest &8211' a tool that creates an interest graph &8211' a list of things you probably love &8211' based only on looking at your twitter stream.

Gravity CEO Amit Kapur explained the product in detail in a guest post on TechCrunch today.

To use it go to Twinterest and authorize it to access your Twitter stream. You may find it does a pretty good job of suggesting things you like. Mine includes Virgin America, &''slap fight&'' (no idea), Facebook, American Express (hah), Google Voice, Andy Rubin and Spotify. Also, Daniel Lyons, aka Fake Steve Jobs.

You can help Gravity refine your interests by re-categorizing or removing any interests that don&'t quite fit. For now this is just for fun. In the future, tools like this can help show you more interesting content and ecommerce items.

Update: Oh! That&'s the slap fight stuff. Very funny. Who doesn&'t enjoy watching a slap fight, I guess.
