Recently, blogging service Posterous thought it would try and help ease the burden of moving from other places on the web to its blogging platform by developing a bunch of migration tools. All of these tools were built on other services' open APIs and designed to go in, grab your content, and republish it through Posterous maintaining as much metadata as possible.

What makes a trip to a restaurant a great experience is not just the fact that they serve delicious food and good wine, but it has a lot to do with the atmosphere and overall 'vibe' of the place. Of course, a 'good vibe' means different things to different people (some like it chilled and some like it loud and bustling), so imagine how cool it would be to be able to browse through dining options based on the exact atmosphere you're looking for. That's what Hoppit is all about; finding restaurants by atmosphere. Hoppit's API provides access to this handy functionality.
