Wouldn't I have to post lolcats and use a lot of private jokes and/or profanity to imitate the wanky fail of FW?
No, but seriously, you and I are unlikely to agree on FW's merits, or even probably its purpose, but that's ok -- that's why there's sites for meta like this one. FW is not for everyone.
Re Alohomora. Yes, I read that. Statistically, you need more than a single example to make a case, but presumably her lawyers have that. As to it being taken from West African languages (heh: almost said, technically correctly, "a West African *lexicon*?)
Maybe that's how she remembers it, and maybe she has notes from 15 years ago. It's always intriguing to see information showing where an author got their ideas. But that doesn't rule out other influences. Our memories are strange things. JKR doesn't acknowledge any debts to the extensive British and fantasy literature, either, yet the traces of those previous works are all through her books, as so many have pointed out.
She does seem to be one of those authors who genuinely believes her ideas are entirely "original." But that 19th-C notion of the Artist as Genius, a uniquely rare person who creates music and art and stories never before imagined, is no longer the prevailing theory of how creativity works. Much of meaning is constructed *between* the reader, text and author, beyond the control of the author.
... In fact, a theory of the textual source of meaning is at least partially behind her legal team's arguments, for them to claim that if SVA's text duplicating JKR's text by more than X%, it's a "violation" regardless of *his* meaning. His lawyers will probably also argue from authorial intention in claiming that his "intent" is to serve different goals than her books do. And the reader-response angle is served where both sides argue that how "the fans" or buyers perceive the Lexicon vs. the Encyclopedia is also critical to defining them as "the same", or different.
Anyway .. I did look at FW earlier; appreciate the additional links, though as you can tell I'm really much more into discussion than one-liner humor. I notice that odd but frequent thing when it comes to HP topics on FW, a whole bunch that ridicule HP fandom, and an even larger bunch adoring JKR. There's some fascinating love-hate and over-identification issues there, but that's for another post someone trained in psychology to explain.
As before, it strikes me that a lot of the posters on FW avidly believe themselves in fairies author-as-Genius, with income and/or popularity taken as the index to "originality." That is, whoever writes more words, or has more fans, or earns more money, is better and more creative. (Insert optional nyah-nyah.) Lots of fallacies there, but again, for another post. Maybe on how bad education is...
