The only things JSON has over xml is that it’s easier to write a parser for it and the format is less verbose and less complicated. There are extensions to JSON that can add features that xml has and the JSON spec doesn’t have. Overall the xml spec is bigger and has more features but that also makes it overkill for many of the cases that it would be used in.
That’s really a lame dividend. I have no idea why the stock would shoot up 15% to $160 on the news that shareholders will receive $0.20 per share. Even with the buyback program it won’t be that big of a boost. The better asset allocation would’ve been to keep innovating but I guess they’re out of ideas?
