Well I noticed this on Jimbo's talk page whilst asking an unrelated question, and thought it was kinda amusing in a sort of 'little bit annoying, little bit funny' sort of way.
Just amusing enough to drop a note in here in fact.
JimmyWales.net and JimmyWales.org are being squatted on.
Perhaps most note worthy is the fact that the .org refers to a version of Jimmy's page which says 'Guten Tag! Heil Hitler! Welcome!' as an intro - now using a public diff. of a wikipedia page to commit a possible libel raises all sorts of questions, no?
ps. this diff seems to indicate that a chap called 'Wayne Smith' who's an 'internet prankster' may be the protagonist in this little sideshow - here's one of his previous japes (from the diff)
