These are interesting points in Matthias’s post. I am not sure if I have fully understood your message here, relating to the wide jumps – I suppose you are referring to oftentimes different literacies and syntax (in and outside the course as proposed by different actors (learners & other networkers).
I appreciate your use of the words – traversing, jumps which match exactly what this course is all about. This reinforces the importance of syntax – the way in which words are arranged and form sentences and context – the words that come before and after a particular word or phrase and help to fix its meaning with the semantics (meaning). For me, I just integrate them in my connection (communication) (cognitively and socially), and so I seldom look into it with such details.
I suppose the juxtaposition of cognition, syntax, context, pragmatics, semantics, change, etc. would help when I draw them up in my mind as delineation. May be it is like driving a car (use of language), where one has to check the tyres, oil, lights, gear, accelerator and brakes (syntax – words in sequence), and the traffic condition (context), which type of car and technique should I use (pragmatics) and wayfind and sensemake (cognitively) in order to drive safely (meaningfully – the semantics).
Have I jump started? Or may be driving in the wrong lane? May be I am driving a virtual one different from yours, but surely we are cooperating, not competing.

Relating to Jenny’s post: Why is syntax particularly relevant for us as learners in the 21st century?
So would my analogy of driving a virtual car make sense? If I drive with the lights on, does it mean that I am driving at night, or in the day time when there was pouring rain, or that I have to signal that my car is on an emergency? So the lights in my car would be like the words that I used, which could carry much meaning to myself and other drivers. Similarly, when I am communicating and conversing with our peers and instructors, any words and sentences used in my post would signify my state of mind and emotions, and thus could be interpreted quite differently under different contexts.
Maria provides a great summary here on syntax
Syntax in linguistics (Wikipedia),“is the study of the principles and rules for constructing sentences in natural languages. (…) The term syntax is also used to refer directly to the rules and principles that govern the sentence structure of any individual language”.
Relating back to pragmatics, I love Ruth’s post here where she introduced Netvibes as a vehicle for virtual driving. I enjoyed the ride….
