Web and social networks are part of our reality, so we must take them into consideration in our qualitative studies (regardless of the specific research theme)
That’s why I always make an online desk analysis with respect to the product/brand linked to the research… most of the times as an “added briefing”, a different perspective where the research/the fieldwork starts from
I‘m part of some communities/online groups on Facebook/Google Plus (different themes/topics), really useful as a personal monitoring/update as well as an qualitative analysis tool (of course, as an advanced/opinion leader target)
