PollDaddy, one of the most popular online poll and survey creation services, recently opened their new API to the public. The basic PollDaddy service provides free accounts for creating polls and surveys, or a Pro upgrade that eliminates sponsored links and allows higher numbers of survey responses than the free version. Now with the API, the core poll creation and reporting services are available to developers (details at our PollDaddy API profile).
The line between what constitutes a software-as-a-service (SaaS) application and a platform-as-a-service (PaaS) environment has always been relatively thin. SaaS applications that expose an API to third-party developers can quickly transform into a development platform.
