The intro portion of the FAQ currently reads
Open Data Stack Exchange is for developers and researchers interested in open data.
for people who don't know what open data is could a bit more explanation could be included?
Here is the intro paragraph from Wikipedia.
Open data is the idea that certain data should be freely available to everyone to use and republish as they wish, without restrictions from copyright, patents or other mechanisms of control. The goals of the open data movement are similar to those of other "Open" movements such as open source, open hardware, open content, and open access. The philosophy behind open data has been long established (for example in the Mertonian tradition of science), but the term "open data" itself is recent, gaining popularity with the rise of the Internet and World Wide Web and, especially, with the launch of open-data government initiatives such as Data.gov and Data.gov.uk.
After reading The 7 Essential Meta Questions of Every Beta perhaps the larger issue to address here is "What should the FAQ contain?"...
I obviously think there needs to be a better explanation of what open data is, however it would be beneficial clarify some other items as well what kind of questions are acceptable to ask here and what kind of questions to not to ask on opendata.
