I loved the idea of the slides interspersed with text. Just posting slides is usually lame, because you lose out on the actual talk, which contains most/much of the actual information.
Yeah, it's an interesting format I've recently started experimenting with for some of my own talks (though only preliminarily). It seems sort of halfway between the "throw up slides" non-solution, and the traditional academic solution, which is to accompany a talk with a written paper. Then the paper would serve as the "durable" version of the talk suitable for archiving, laying out the same material but in a way more suited to text, and usually a bit more formally, with more details (e.g. to enable someone to actually reproduce the work).
The slide interspersed with text format could be seen as a more heavily illustrated, easy-reading sort of paper. More similar to the talk than a traditional accompanying paper would be, but not just the slides. But I think it's still non-trivial work to make a good version, which is why people often just throw up the slides, because that's almost literally no additional work.
You basically have to take the same source material and think how you would write it up into a blog post, which is not 100% the same as thinking of how to give it as a talk. Though I guess a first-cut solution could be to just record the talk and type up a transcript in between the slides.
You could probably do a lot worse to prepare for a talk than writing such a text+slides version of it, then distilling key words as notes from the prose and then practicing and giving the talk based on those.
A lot more work. Like a lot of people, I don't read some kind of static text to an audience; even with the same slides I give a different talk every time. The only way to put together a page like this one would be to simply transcribe the talk. If somebody has the time to do that, that's cool; I sure don't.
I don't know if it really would be that more work if you planned it from the start. Granted, I'm not very good or experienced at presentations and public speaking; so when I do I tend to spend a lot of time preparing. This preparation invariably involves practicing the talk a lot and writing down key words to remind me of points I must not forget. I suspect that writing the talk out at some point during that process would help just as much as (if not more than) spending the same time practicing the talk a few times. I'll certainly try this next time.
