I agree. From a startup standpoint we are able to decrease a lot of expenses by simply utilizing public API's. The advantages of open source code for companies meant that you didn't have to go out and purchase software. We are seeing the same thing with API's. The only problem I see with this trend is the dependency of those API's. With open source software such as PHP & MYSQL once I have it installed, I own it, where API's are real time dependency i.e twitter going down, will cause twitter dependent applications to go down as well. As as a developer myself the value proposition is that the data is also available with the API.
