Before I started the course I had not thought much about hypertext beyond simple links. In the two weeks that have gone by I have already begun developing an appreciation for the richness and complexity and power of this toolset.
In terms of actually working with Tiddlywiki and the other course materials, I often feel confused. There's a lot to figure out and remember between all the different workspaces, course communication vehicles and the Tiddlywiki language itself. The step-by-step videos and tutorials you make definitely help. I learn best by example and by doing. I feel like I will eventually get comfortable - the beginning is always the hardest!
(One thing I had trouble with was watching videos where you share your screen. Turns out I need to wait until you start screensharing before I open up to full screen or all I see is your head while you talk. Thought I'd mention it in case anyone else has the same problem I did.)
