Okay, it's easy but it's complicated. It is difficult to write for both the people who are most likely to read what you have written because they are most likely to already know what is here. Then there are the people who you don't know who might stumble upon this and actually read it--that's an entirely different audience who knows nothing about me and my background and depend on what I write to make sense of what I am saying. And then there is myself--I blog for myself, as a kind of personal history and because I enjoy it. So, it makes it hard to know what to say, what not to say, and just how to say it. And that's my two cents on blogging.
