Interesting that you both collected data in the same sort of way, through SKYPE interviews (what I refer to as "video calls" in the book, to minimize use of brand names ). But you analyzed your data very differently-- one focusing more on audio, one more on text, but neither on the visual data from the SKYPE camera feed.
In literature about interviews, much is made of visual and eye contact, as well as on non-verbal communications. Four modes of nonverbal communication are as follows:
1. Chronemics refers to the use of pacing and timing of speech, and the length of silence before a response in conversation.
2. Paralinguistic communication or paralanguage describes variations in volume, pitch, and quality of voice.
3. Kinesic communication includes facial expressions, eye contact or gaze, body movements, or postures.
4. Proxemic communication describes the use of interpersonal space to communicate attitudes (Gordon, 1980; Guerrero, DeVito, & Hecht, 1999; Kalman, Ravid, Raban, & Rafaeli, 2006) .
To some extent we get Chronemics even in text-based interviews based on timing of responses. A big advantage of rich synchronous communications that you have the ability to bring more visual and non-verbal dimensions into the interview-- as compared to a text-based or email interview where questions are posted/sent and responded to in writing.
That said, as you both have noted, you got what you needed from the verbal-text responses. Again, the whole point is to match technology with purpose. If the camera is a distraction for what you are trying to do, turn it off altogether or use it for a quick get-acquainted hello then turn it off.
On the other hand, you have another set of data that you might later decide you want to look at, analyze and discuss.
We are on a new frontier here and thoughtful discussion of experiments is useful for moving this kind of data collection forward.
