I don't think similar answers are useless. I think that especially in a language such as Perl where there are many ways to do the same task, that it's validating to a point when people agree on "the way" to do something.Obviously the conscenus is not always right but I'm willing to bet the majority is usually right at the Monastery.
I'm also not inclined to write a post then while previewing, open up another window to make sure that someone else hasn't said what I've said before I've posted.
