Stannp.com is a free app that allows users to quickly and easily create their own custom-made postcards. The company provides the Stannp API that allows developers to integrate this tool into other applications. By snapping a picture or using an existing image, the user has the option to customize the image with fun effects and add the finished product to their Facebook wall, email it to a friend or have it turned into a real postcard to be posted the same day.
Another day, another API... Keeping on top of all the APIs that have been made public to support the plethora of web services that are available these days can be a full time job. Yahoo thought so too, and so they created the Yahoo Query Language (YQL), which provides access to hundreds of web services with a single SQL like syntax. And now YQL supports Google Buzz.
While social networking sites already help users maintain connections with friends and interest groups, a recent trend in web services has been the growth of semantic technologies that connect people across different websites. New York startup AdaptiveBlue offer a service called "Glue," which uses semantic web techniques to understand the content of popular web pages that describe lifestyle objects such as books, music, and movies. It then lets you do many useful, in-context things based on that data, such as learn more about the movie or actors on IMDB, buy the soundtrack on Amazon, read the historical background on Wikipedia, and a interact with a variety of other sites and services.
