Methods to Study Digital Media

I'm teaching a class next week on "Online research: New challenges & opportunities". In preparation, I was thinking of all the ways to study online (and by this I mean both Internet and mobile) phenomena and to use online methods to study other things.

As I love typologies, I thought I'd prepare one on this.  Although such a list doesn't express the complexity of online research, I thought it would demonstrate the diverse ways to investigate digital media.

Online methods to examine online phenomena:

• computer-captured and compiled data (e.g., web metrics)
• email, virtual reality, VoIP telephone or video call, or instant messaging interviews
• diarying or user logs
• remote observation (participant or nonparticipant)
• online focus groups
• web-based or email surveys
• audience response systems
• remote user testing or experiments
• autoethnography (can be conducted through blogging)

Methods to analyze online phenomena:

• social network analysis
• semiotics or visual analysis
• content analysis
• discourse analysis 
• hermeneutics
• ethnography

Online methods to study offline phenomena:

• web-based or email surveys
• email, virtual reality, VoIP, or instant messaging interviews
• diarying (e.g. through special software or blogs)
• photo documentation via mobile device

Offline methods to study online phenomena (which may or may not involve having users interact with digital media while capturing data):

• face-to-face interviews or focus groups
• nonparticipant observation
• contextual inquiry
• verbal protocol analysis (talk-aloud method)
• eye-tracking studies
• user testing or experiments

As a colleague pointed out there's also design science and participatory design that involves creating digital media as research tool - this type of research could be place in every category.

Please let me know if I missed a major method, as I'd like this typology to evolve iteratively.
