I saw this on Slashdot this morning...
I think its fucking nuts. I mean, my last name is Arp, which also happens to be a networking protocol. Do I have to worry about being sued by some corporation someday? Am I out suing people? Look at these:
www.arp.org
www.arp.com
www.arp.net (redirects)
www.arp.cc
Microsoft needs to leave this kid alone, though you've got to admit he was asking for trouble when he bought
www.mikerowesoft.com instead of mikerowe.com or something.
