Open Source Solutions
When examining the WebSM database, one finds surprisingly few open source web survey solutions. The most surprising fact is that there are not many advanced tools, whereas that does not apply to certain other areas (e.g. CMS) where many powerful and advanced open source solutions exist.
The most popular of the open source web survey solutions is probably LimeSurvey, which – although advanced – is conceptually somewhat outdated because it requires a local installation and does not include the level of interactivity that Web 2.0 offers.
