How Did You Develop Your Blogroll

Hello boys and girls. In the past I have asked you for your feedback on many different aspects of blogging including but not limited to:

How Many Blogs Do You Read?
Do you Have Blog Envy?
Bloggers- Do their pictures match the writing?

And now I am curious to get your input on how you developed your blogroll.

Do you blogroll everyone who blogrolls you and if so, do you blogroll bloggers whose blogs you do not read?

Is it more important to you to have a “comprehensive” blogroll or one that is only composed of your “favorite” blogs?

Has your philosophy changed at all since you first began blogging?

When you first began blogging did you copy the blogroll of the blogs you thought were the coolest?

I am all ears now.
