I made this observation at work today to a grear co-worker, who should have her own blog,

"It's funny but after years of working on documents here it always makes me laugh that people tend to put 3-5 linefeeds or carriage returns at the end of their documents - they could just accumulate there during editing, but often I think that people just want to make sure nothing creeps up from the bottom of their text :) - like a moat on their intellectual castles. lol"
