This Week in Mashups: 24 APIs Used in 7 Days

Each week here at ProgrammableWeb we have dozens of new mashups added to our mashup directory. And each week these applications use dozens of different APIs, often in unexpected ways and in unique combinations. For example, this past week there were 23 new mashups added which in total used 24 different APIs (some APIs were used once, some many times).
