Keep it on the hush

Today, I have a question for you ladies. When did you feel comfortable openly talking about your blog?
Blogging is something I started for me to document my journey over our engagement, and then I decided a few months ago to keep it up past our wedding. Which is why I decided to go ahead and change over the name to something a bit more general.  I've just passed my 100th post (yipee) and I'm started to feel a bit more confident in my "blogger" title.
SOME of my close friends know about le blog, all in all it's probably about 10 people. That is as far as I have felt comfortable with. I've been asked by co-workers before (I work at a Blog/Social Media Company) but I haven't said that I have a blog. Although, a part of me is thinking I should - just to start doing fun campaigns. It really just isn't something I'm comfortable with disclosing. I feel like this blog is  a little private to me at the time, and quite honestly...I'm scared of being judged.
Is there a point that you felt comfortable enough to share your blog with other people? Or just generally talk openly about it? 
It's weird, but I feel like I'm almost living a double life.  My real-world life, with my friends, family and all that jazz. And, then my little circle of blog friends - it's like a nice little house in the pleasantville where everyone is encouraging and helpful.  Plus, let's just mention that it's REALLY nice to have an outsiders opinion on things like pinatas and mean girls.
Sorry for the short and random post today, but I really can't wait to hear your thoughts! 
Have a great weekend :)
