How straightforward is your profile? Did you pad it up to make yourself look good? Don't we all?
Truth: I have read the profiles of the people whose blogs I read; and it is my observation that most writers are self-deprecating, if anything. It is more likely that the blogger is much more brilliant, a much more accomplished writer and observer of the human condition, a much more well-rounded individual than the profile might lead you to believe. But read a blog for a while, and you will get a sense of the person, regardless of what is written in the bio.
