One of the smartest things about web services are the APIs, which let you take data or content from one service and wrap it up in experience from another service. Mashing services together often results in the whole being significantly greater than the sum of the parts. Take for instance, Instagr.am, which combines cool photo filtering along with an instant network to share your photos. Then, make all of these photos accessible by exporting them to them available through popular social networks that everyone uses like Facebook and Twitter and you have the ability to expose your photos to a much wider audience. You can embed your Instagr.am photos nearly anywhere making it effortless to amplify the reach of your photos.
I believe the next big API target is music. With services like Pandora, Last.fm, Rdio and Spotify, there are no shortages of companies who see the potential in social music. The beauty is that sharing music is something people have been doing for decades, through mix tapes, going to concerts and loaning CDs to each other. The behavior doesn’t need to change in order for it to work; rather, the technology needs to catch up with how consumers expect to discover new tracks.
