My writing is sometimes influenced by the people I know read it on a regular basis. One friend reads every Saturday. (Hi, Ros.) A couple of friends often say they like my writing. (Hi, Leslie and Susanne.) And there's my family. (Hi, Cyn, Maggy, Sarah.) Even some political colleagues. (Marty, is that you?)
But I wish more of my friends had blogs to share. It's easy. At the top of this page, toward the right, is a button for "Get your own blog." Blogger will ask you to make up a user id. Don't agonize over this - it's never visible to the public. Then you have an opportunity to name the blog and choose a template to control the appearance of the blog. Again, no need to put too much effort into it - it's changeable.
And you're off. Writing the posts is no more difficult than writing email.
