I am afraid I have not been nearly so adventurous to have any serious regrets. My biggest regret is not having enough time to participate more than a couple times a week and taking so long to join the blogosphere.
Even though my blog's been up over 2 years I still consider myself a newbie, since it was only this year I joined a blog hop and did a guest post or had more than 50 visitors for a single post.
I look forward to learning a lot more (and I am sure I'll have oops! stories to share along the way).
Leave me a comment, even if you don't find a mistake! Thanks.
