Social news filter Digg has spawned imitators, including Reddit and Slashdot's Firehose. Oh, and the late, unlamented Netscape. "Ripping off" is practically a core tenet of Web 2.0, though we suppose it sounds nicer if you call it "iteratively evolving industrywide best practices." One creative Web designer and Xbox fanboy, though, decided the Internet needed a Digg dedicated to Microsoft's Xbox consoles, so he created Diggxbox. As you might imagine, it uses its own version of Digg's user-driven filtering to sort the day's Xbox-related news. It's even adopted cute videogame touches like the Xbox's "red ring of death" as the "bury" button (as Digg's mechanism for voting "no" on a story is known). Cloning Digg is easy, but attracting a fanatical userbase like Digg's is another thing altogether.

Digg, of course, has its own thriving videogames subsection — so Diggxbox's creator posted an advertisement for his site on Digg. His Digg account was subsequently banned. Apparently founder Kevin Rose doesn't view amateur imitation as flattery. On the other hand, this diggxbox chap should be pleased he escaped with a mere banning instead of say, a trademark-infringement lawsuit.
