If they didn’t have questions, I don’t suppose they’d come. They seem nice.

Making videos is easy. Making a wiki application using Xtreams PEG grammars (i.e. PEGParser class >> grammarWiki) was hard. I had to figure out how to write an actor subclass to PEGActor. That, for me, was extremely difficult. http://www.ooplu.co <http://www.ooplu.co/>m as a web page doesn’t look like much, but it is now a bootstrapped Ajax wiki on top of Altitude called PEGWiki. Extending PEGWiki’s wiki grammar to include videos from Wistia [1] and making the videos is trivial compared to me trying to understand Michael and Martin’s agglomerations of blocks within blocks with stack arguments constructed by pragmas as single values in a dictionary. Oh my. Although I can use it, I still don’t really get it. 

I’ll show it at my presentation.
