Personally I think the "fluid" responsive design for article snippets is a mistake; but then I hate multi-column feed designs, so that may be just a personal preference.
Apple got it right with the iPhone menu structure, which was inspired by the iPod (maybe they nailed it because it was not card-based). There, columns always maintain the same positional relation (there are menus to the "left" and sub-menus to the "right"), so you can always remember by muscle-memory where a particular item is located relative to the others. Re-flowing similar items breaks those relations.
Responsive pages make sense when the side columns are used for side content (i.e. "aside" tags, headers and footers, navigation...) - there, placing the sub-content above or below the main content to show it on a narrow screen is not a problem, since the moved card was subordinate to the main article anyway.
Not yet. To be honest, I've just decided to focus on backend features, put a locked height on items and to get back to this in the "let iterate on design details before releasing" phase.
But those plugins are a perfect fit that I didn't know of, thanks for it !
It's still something that have to be done through javascript, though. So I guess we probably have to consider cards canvas as a feature rather than as a design element (like calendars, graphs, etc).
