Yes John...good question. I always thought Java was "bad".

[John Robinson]

There's Java, a slow-loading resource hogging beast, and there's JavaScript, which is fairly light and enabled by default. They're different creatures. I'm talking about using the light and nimble JavaScript.

Yes, there are very good reasons to disable JavaScript. JavaScript is not itself dangerous, but bugs in JavaScript can be exceptionally dangerous if leveraged by a malicious website. Additionally, certain types of bugs in websites can become dangerous when JavaScript is enabled and exploited by malicious visitors. These are all good reasons to disable JavaScript. But, for the most part, JavaScript is enabled in the majority of browser installations.

Any use of JavaScript on this site will have a non-JavaScript fallback for those with it disabled, such as defaulting to the US/Eastern time zone. The sole point of JavaScript being to enhance functionality, not replace it. The benefit of shifting this enhanced functionality to client-side JavaScript far outweighs any negative implications.
