Students Speak Up in Class, Silently, via Social Media

It seems the more reliant we become on screen-to-screen text rather than face-to-face conversation, the less proficient we will be at face-to-face conversation. But at the same time, this could be a way to bring people out in the open and encourage them to get involved in all kinds of discussion, whether screen-to-screen or face-to-face.
I would be inclined to measure the results. Use the technology in one class but not in another. On the last day of class, don't use it in either class, and see which class has more face-to-face participation, the one that had to do it from the beginning or the one that got eased into it.
It's much harder though to measure the long-term consequences. If technology like this continues to become more and more pervasive, there may be no "last day of class" in which people are forced to speak up. The analogy to physical exertion is well warranted. It is now possible, because of technology, to live your entire life without engaging in strenuous physical activity. This was simply not the case even 50 years ago. In another 50 years, will it be possible to live your entire life without engaging in face-to-face conversation? If so, do we want that?
I think the main reason people don't speak up is social - it's not seen as a cool or valuable thing to do by peers (and I've seen that even at university level in a self-selected group interested people, for anything beyond small groups, except with exceptional lecturers).
Chatroom style interactions seems to somehow change the dynamic somehow. One of the better set of lectures I had used an everybody-vote-on-answers-to-problems format, and because you're not singled out, there was much more engagement. It also gives the lecturer/teacher more input (whereas volunteers I think are often on extremes of ability curve).
People often seem to think of discussion-style teaching as being a social science/humanities thing, but it also works surprisingly well for math, computing, and science. I think a lot of people have the idea that in more technical courses, you have to do lectures (maybe with labs) because you're basically trying to teach a bunch of information. Most schools focus on teaching technical skills and knowledge, and expect you to just pick up on how to think as you go along.
Turning that around--teaching thinking and letting students pick up technical skills from examples--seems like a better idea because technical knowledge progresses so rapidly and because technical skills are easier to pick up. It also enables discussion-style teaching in math, computing, and science. Instead of listening to a lecturer spew material you could have found in a book, you solve problems together.
(Aside: interactive learning is really the only way to justify the high cost of college from an educational perspective. Ignoring stuff like networking and partying, it seems like going to a school where they teach by lecturing is a waste of time and money, since there are so many free lectures available online.)
The "everyone vote on answers" format is a surprisingly effective way to improve engagement in lectures. They get people to pay attention, they give you in-class feedback about what you have learned, they give the teacher more input (like you said), and they make lectures a bit more fun without being too cheesy.
Another simple technology-based way to improve engagement is to have students post their writing for class (reading responses, essays, etc.) on a forum. I took a class once where, instead of sending the professor a reading response for every class, we posted a reading response to a class Facebook group once a week. We were also required to write at least one substantial reply to others' posts once per week. The interaction was awkward, at first, and some people did the bare minimum the whole time, but after a few weeks a good chunk of the class was posting more than they were required to on a regular basis. Besides simply improving engagement, it seemed like it was making people think and write better, probably because they knew their peers were going to read what they wrote.
The only real disadvantages are that typing is a little slower (I type around 90 WPM but speak around 150 WPM) and that you don't get body language cues in writing. For the sorts of things I am interested in, though, I actually prefer not having body language. Body language makes us try to react to others by guessing their mental states from some subtle changes in their shape. This is problematic for two reasons; first of all, this sort of guessing is inherently imperfect, but more importantly, we tend to be quite heavily influenced by our perceptions of others' reactions. (This makes sense, evolutionarily; it is a way of making us cooperate and preventing us from diverging too much.)
What this means for conversation is that topics are chosen, opinions are suppressed, and minds are changed purely on the basis of our faulty readings of others' opinions. This is especially problematic when talking about abstract ideas because subconscious emotional reaction is an awful predictor of the merit or validity of ideas. The problem is compounded because we are very bad at simply setting aside our reactions, especially in social contexts.
Body language heuristics are obviously good for some things. They help us negotiate relationships, know when others are upset, and interpret ambiguity. But they also give us false impressions and lead to socio-cognitive biases. Furthermore, a large proportion of the benefits of body language come from dealing with problems of face-to-face interaction between primates, meaning that the benefits are less when dealing with textual communication (and especially communication about abstract ideas).
Even small talk over IM seems to be more stimulating to me on average than face-to-face small talk. I have observed this not only in my own interactions but in watching the interactions of others as well. My sample could be biased, because I am obviously a nerd who mostly hangs out with other nerds, but I think I've seen enough "normal" people to make a general statement. Your mileage may vary if you have different tastes in conversation than I do. But if you prefer to talk about the abstract or the complex, or if you try to avoid cognitive biases, then the only way I can imagine face-to-face conversation being generally preferable is if it has a strong instinctive appeal to you.
A lot of people do seem to have this innate preference. The same people often seem to prefer reading on paper than on screens. Some of them say their preference is based off of eye strain--which might even be a reason to prefer speech over text--but for a lot of people the reason seems to be more aesthetic.
That brings me to the second huge benefit. When talking, you will very rarely speak at the same time as another person. Not only is it rude in basically all cultures I am familiar with, it also makes it hard to follow what either person is saying. With text there are no such limitations. When you consider that an average person can read up to 300 WPM, while someone that has practiced speed reading can easily break 600, it is not too infeasible that both sides of a conversation may be typing the vast majority of the time. For those well practiced in text-based communication this can greatly increase the average amount of information transfered per unit time, easily negating the difference in typing vs speaking speeds, and possibly even improving upon it.
I do agree on your notes about body language and emotions. I have lost count of the number of times I have seem people interpret sarcastic textual statements to be completely serious. On the other hand I find that people get better at recognizing even that when spending enough time reading chat/comments online.
