Thinking about Blogging

I love reading other peoples blogs and getting fun updates and pictures from them. I do not like facebook and updating that way, but I feel the pressure from friends to provide updates. So, what does a mom of a newborn choose to do? Spend 30 minutes once a week and blog, so close friends and family can see what is going on, or do I send out email updates . . . ? Also, having a husband who is very keen on Internet Security, I need to be careful with what personal information I put out there on the World Wide Web. So I think I'll try blogging and updating those I love in this format.
