The blogosphere is awash with those who believe the more words, the better. A perfect example is Jim Quinn and his Burning Platform. Another is RE over at the Diner, of which (and whom) I remain a fan.
The problem with using a lot of words is that those who wish to ignore or undermine you can latch onto the words that matter to them and ignore the rest.
The better you are able to deliver meaning with few words, the more of what you mean to say will make it through the filters of others unhindered.
The irony here is that even this short post is capable of igniting an irrelevant and distracting controversy (over who v. whom).
