The blogosphere

It seems that a lot of people are writing/reading blogs these days. I love it- it's a great way to connect with friends and strangers alike. I do however have a few questions for those in the blogosphere.......

How many blogs do you subscribe to/have on your reader?

What are your top 3-5 favorite blogs?

Do you have a blog? if so- why/when did you start one? how often do you post?

Enquiring minds what to know!! I realize we do not have many readers but I'd love to hear from all of you:)
