Dave, if you could go back in time, would you have used JSON instead of XML for RSS, OPML, XML-RPC, etc, had JSON been popularized at the time? - FriendFeed
I liked Dave Winer's response on the perceived overhead of parsing xml:
when we wrote our XML parser for Frontier, in C, the typical machine
ran at 200 MHz and had about (guessing) 100MB of memory. Obviously
today's machines are much bigger and faster, yet people *still* raise
the encoding and decoding perf issues as if they matter in 2009, I
don't see any evidence that they do.
I think he is right, parsing xml, while I'm sure it is slower than parsing json, I bet it isn't that much slower. Today's computers are so fast that parsing text is almost a non-issue, no matter what transportation format the text is in.
