I agree, a confusing survey (I answered the question about 'websites' thinking of discussions forums including this one, only to find there was a separate question about them. And how do they define "social media"?)

I would have found it much easier to give meaningful answers if they had asked structured questions about the individual topics they are researching:

Personal Learning
Session Recording
Private Collecting
Online Discussion
Specialist Research
Technical Development
Public Organisations & Initiatives
