I suggest that before anyone mocks anyone further, they search Google for [translate flags babelfish], then click images, then click a few of the now-easily-recogniseable flag images that turn up to look at what is a generic feature used in several places. I doubt Pangolin own a patent on the document.write() method or those flag images, or the standard Babelfish URL and JavaScript syntax.
Emulating an idea isn't theft. Direct copying might be but the standard of proof should be higher than I saw here. A lot higher. What I saw could be construed as public libel and defamation. I might be silenced if Bill can provide legal proof that Pangolin originated the idea propagated by Babelfish and Altavista, but I suspect that none exists.
I've made what could truly be a unique bit of JavaScript code on my own site, tucked away where no-one is even likely to notice (although some of those who have seen it have commented on its unusual ability). I know it's unique because of the long time I looked for it before deciding I had to invent it in the absense of anything like it. I couldn't even find help towards it on the expert sites for coding examples and such, short of basic descriptions of the methods I eventually chose to build my code with. It guarantees that no matter how the page is called, linked to or loaded, it ALWAYS indicates the actual page the visitor is on so long as the frameset is intact because that code links through the whole frameset even though it's extremely compact. If someone copied that I wouldn't mock, I'd probably ask them out of curiosity where they got it, but I'd be glad to see it put to good use.
Obviously my last paragraph might easily be dismissed as irrelevant but not by me. Coming up with a really unique idea is usually likely to make a person want to see it propagated, not to guard it jealously and mock someone for using it just because they didn't ask.
