My organization uses FluidSurveys for a variety of in-house research: this includes internal and external surveys as well as e-consultations. My team, in addition to our advisory role for the organization's public opinion research, also serves as an administrator of the system: we manage accounts, assist in programming surveys and gathering data, and reporting on the data. In this sense, we serve as the gatekeepers for the system, which is used across the organization (including in our regional offices, although most of the work is undertaken at HQ). Over the past few years we have implemented dozens of surveys using FluidSurveys, including high-profile public e-consultations which have received thousands of responses.
FluidSurveys has allowed for both opinion-gathering and non-opinion information-gathering, as it's amenable to more than just typical surveys. (We have used it to gather input on annual reports, for an example of the latter.) It allows for a collection of info in a centralized area, using a very intuitive and flexible system. The system obviously is a major improvement over paper surveys in terms of ease of implementation and collection; it also presents a cost-effective solution when contracted research isn't possible.
