Are you more or less likely to continue to blog if no one is reading or commenting on your blogs?

For example: If you know that no one is going to read what you write, do you think you would be more liberal with the information that you put down?
or
If you know that a lot of people are reading your blog are you more apt to posting more often and with greater details so people know what is going on?

On the other side of that:
If you know a lot of people are reading would you be more careful of what you say and how you say it?
or
If you know a lot of people are reading would you say what ever you wanted and just spill your life in to the digital world?

Just curious, let me know.
