How to answer questions
You should pick the type of answer you are comfortable with and feel you can truly add value to the discussion with. The benefit of PM is that someone else will cover every possible way of answering them. :)
Further tuning of your posting style can usually be done by dealing with the comments to your comments and voting you get.
That said, I tend to try and find something unique to add to the discussion when I post these days.
$you = new YOU;
honk() if $you->love(perl)
