The use of "hipster" as a pejorative doesn't even make sense to me here. HTML, CSS, and JavaScript are hipster technologies? They aren't new by any stretch. Using this term seems like lazy authorship and thinking. Instead of explaining, just call it hipster and assume it's obvious. Like you said, cross-platform support is the opposite of unimportant. The appeal of the web has a lot to do with the fact that a browser on any platform can (mostly) have the same experience without (too much) extra work. It may not be appropriate for Light Table, but a general hipster-like dismissal of web tech doesn't advance the argument.
