Slashdot chose to run the .org as their main domain. If they had bought the .com the .org would never have been worth as much as it was in the reverse case.
My point is that for a while, somebody ran a .com which put .org in an iframe and put advertising above it.
If Slashdot had owned the .com, it wouldn't have happened.
An Australian example is crikey.com.au, who for years were troubled by people referring to them as crikey.com -- in print media, on TV, even in Hansard.
