Yes it's the old debate, endlessly rehashed. I just want to point out that Peter's pronouncement is controversial, so newer members don't think the issue is settled.
I started greasing tapers 30 years ago and haven't seen a problem with one I assembled yet, including cranks ridden by top amateur racers (including several US National sprint champions) and one 50k mi/year multi-time Race Across America competitor.
Others report similar success with dry tapers, yet some people do have problems with that crank/axle interface, whether dry or greased. So I think it's clear that neither way is guaranteed to work or not work - there must be other factors at work here that are equally important or more so.
People can take a side of course, but I think it's fair to mention the fact that it's controversial.
