I support a name change. Frankly the only people who would find "NIPS" amusing are those with the minds of 12-year-olds, but --breaking news, not!-- there are a remarkably high number of such folks in attendance at conferences. Including this one. So why give the puerile crowd anything extra to exercise their little minds over?
There's nothing inherently wrong with a name like NIPS. But the record of this and other similar conferences makes it susceptible to a rule I may as well call This Is Why You Can't Have Nice Things.
