I had to stop counting when I got to 40. A lot of the folks are friends and family who live far away, so it is a great way to stay in touch. Not everyone updates regularly, but I have them in my Google Reader so I know when they do!
I've also met people whose blogs I read before meeting them. That is always a lot of fun.
I know a bunch! But then I help people design blogs for a living, and I'm part of a few local blogging networking groups. Anymore it's hard for me to believe people don't know what a blog is because it's such a big part of my life.
Ok, I'm gonna say about 12 and most of those are my missionary friends who blog to stay in touch with their friends and families back home! My sister and one other friend are my only "real life" bloggy friends...so sad! :)
3, My Mom who does it not so frequently because she forgets, my Uncle & Aunt who are better than I am about keeping it up to date. They live in Indonesia right now so it's a good way for everyone in our family to keep up with them!
