Thinking about Making a Knitting Blog

I'm thinking about making a knitting blog. There are so many knitters out there with their own blogs - seems the right of passage from beginner to intermediate. But won't it take time away from knitting? Ebay is already a black hole, do I need another? Do I need another thing in my life that is less than neat and tidy and calls to me, nags to me, to come take care of it? Plus, I don't have a cat and it seems a prerequisite for making a knitting blog. Hmmm....
