509U6 - Are wikis <, >, or = to face-to-face interaction?

I have to admit that over the duration of this course (CALL), I've been struggling with the seeming preference of technology over people. So, when I found this article Collaborative Composing an Argumentative Essay: Wiki versus Face-to-Face Interactions by

Shokoufeh Ansarimodgaddam from the Islamic Azad University of Tehran, I immediately started reading. The research was conducted by splitting a class in two groups (face-to-face groups and wiki-groups). Each group was to work on the three steps of writing an argumentative essay (planning, drafting, revising) through their assigned medium. Below are the main points of the results concerning how each group fared at each step of the writing process. 

Planning

Face-to-Face:

-group had more flexibility about how they wanted to collaborate with one another

-more specific usage of time (generate ideas together, alone, regroup)

Wiki:   

-never met together in person and therefore had to generate their ideas on an idea page in their wiki

Drafting

Face-to-Face:

-members interrupted each other which led to some forgetfulness/distractedness

-group members could met and discuss ideas with greater ease and in real time

-being able to read body language and facial gestures led to greater understanding between group members

Wiki:

-could generate more ideas more quickly since they were online anyway

-members had more time to think and experienced less interruption

-time consuming because it was difficult to set a specific "chat/collaboration" time

-to compensate for lack of gestures, emogis/underlining/etc. were used but understanding was lost

Revising

Face-to-Face:

-many different people were able to look at the document and point out a variety of errors, this occasionally led to disagreements

Wiki: 

-most editing comments were limited to word choice or grammatical concerns

The article ended with this quote.

"These findings do not degrade the benefits and advantages of face-to- face collaborative writing but rather show that wiki can be used as a continuation of face-to- face collaborative writing that makes interaction and collaboration easier and more effective" (Ansarimodgaddam, pg. 17). 
I'm relieved to find that professionals in the ESL/EFL community found substantial evidence that wikis (and I would extend that to technology as a whole) is = to face-to-face interaction. Technology has it's place and it is imperative that we as educators understand what its strengths and weaknesses are so we can use it properly. 

Final question: Does anyone else have a similar experience with incorporating technology in the classroom?
