how effective is this thing?

whats important in a blog? direction is of ccourse important. i have changed mine about 800 times. i am now going in the direction of personaly updating. really i suppose readership is important. how do you capture tons and tons of readers? i will be writing with the updates in my life. career goals, reading, successes, and overall happiness. i have found that just writing for myself is what ultimately satisfies me!
