I've gotten some pretty harsh feedback on my blog. Friends say I sound cocky and the writing is aggressive. I've told them that if I wrote slowly and deliberately (like I do with persuasive essays), I wouldn't be able to write as much as I do. Everything would take longer. And the posts themselves would be longer.
As a result. I write... Differently. And quickly - for example this blog is being written on a plane, on my iPad. Takeoff in 4.
Anyway, I'm currently reading Getting Real (37signals). And I saw this preface:
"If our tone seems too know-it-allish, bear with us. We think it’s better to present ideas in bold strokes than to be wishy-washy about it. If that comes off as cocky or arrogant, so be it. We’d rather be provocative than water everything down with “it depends...” Of course there will be times when these rules need to be stretched or broken. And some of these tactics may not apply to your situation. Use your judgement and imagination."
While an instructional piece is different than blog posts, I agree that this writing style is best for communicating complex thoughts efficiently. Well said.
