Or would you? Perhaps something that you wrote which no longer fits in with the image that you want for your blog, or something that you posted and then later regretted?
I haven't, and I don't want to, but sometimes when you write a blog post it's easy to forget that you are opening it up to many people, and it's easy to post something without thinking about how other people may read it. Or else you find that your blog is heading in a certain direction, and some posts no longer seem relevant. I don't have many readers, and sometimes I forget that I'm not just writing to myself.
Would love to hear what others think.
