I know slashdot is big on the groupthink, and apple is evil yadda yaddah, but has anyone bothered to look up words and see the different treatment of them?
Now I'm not saying that words per se are bad things (they're not, although I personally prefer to keep them out of regular usage for impact), but I can see how this dictionary might include many more vulgar words and expressions than a regular dictionary. I can also see how a parent could object to their kids downloading a dictionary with such an extensive ouvre of modern vulgar slang.
Let's say you're a parent, and your 10 year old (yeah you spoiled them a bit by buying them an iPhone, whatever, they did their chores, got good grades and are working it off mowing the lawn) asks you if they can download a dictionary app. Would you not be a little concerned if the dictionary was so heavy on modern swearwords? Would you expect this from a "dictionary app"? Wouldn't you expect that the urban dictionary app have a bit of a warning that it might be really offensive, racist, etc.?
Sure they'll learn all these things in due time, but I don't think innocence is such a horrible thing that needs to be stomped out. Kids should allowed to be kids.
