By the time (the Leaning Tower of Pisa) was 10% built, everyone knew
it would be a total disaster. But the investment was so big they felt
compelled to go on. Since its completion, it cost a fortune to
maintain and is still in danger of collapsing. There are no plans to
replace it, since it was never needed in the first place. I expect
every installation has its own pet software which is analogous to the
above.-- Ken Iverson
