Respondent.

Think about that word for a second.  Many of us in the market research industry use it day in and day out, yet we probably don't pause and think of the connotations.  A quick search comes up with the following definition (courtesy of the Market Research Glossary of Terms):

"Respondent - This is the individual that provides data to be collected during the research process. Also referred to as a unit, unit of analysis, participant, experimental unit, or subject."

To me, a "respondent" is someone who is merely asked a series of questions in a 20 minute survey and kicked to the curb for the next "experimental unit" :-) 

Is this how we want people to feel about research?  This certainly isn't what I think of when I see people interacting in online research communities, sharing their thoughts, connecting in meaningful ways and generally enjoying the entire experience.

Here's to hoping that with new research methods we can develop a common language that respects the ways people now interact with us...
