I went from Extreme Markup, an XML/markup conference in Montreal, to TypeCon, a type and typography conference in Boston. From people many of whom think that style is just irrelevent rubbish that gets in the way and it's all about to content to people many of whom think content is just irrelevent rubbish that gets in the way of the design :-)
Both conferences were packed with thought-provoking presentations and cool people. TypeCon had more naked ankles. The conferences overlapped (ironically since a major topic at Extreme is computer representation of overlapping and interwoven herarchies), so I missed the start of TypeCon, but I was there in time for the trip to the Boston Printing Museum where there are also some really kind and interesting people, and where you can see literally hundreds of thousands of drawings for (mostly Linotype) typefaces, as well as old presses, a working Linotype machine, several non-working Monotype machines, visit the library, and of course sign up to be a Member :-)
Came back to Montreal by 'plane, now on the train to Belleville (via Kingston) and thence 45 minutes' drive home. I hope I'll find time to work on helping pango/gtk+/fontconfig to cope better with Expert sets and opentype features, although it's more likely I'll do things like send fonts and mockups to developers so they can understand the problems: sharing understanding is more useful than sharing code, sometimes.
