If you read bylines closely, you might have seen the article on tracker dogs was by a different author: I invited Dr Manhattan to be a guest blogger.

I have no delusions of grandeur about holding a monopoly on ideas or material worth sharing. If you would like to contribute or share something on the blog, you’re most welcome to contact me.

There are feedback widgets on the lower-left of the blog page; hyperlinks at the bottom of each post to email me; and a contact page too.

Perhaps you might like to write a piece as a guest blogger? Or leave a comment under a post? Or if you’re the modest type, you can suggest something using any of the various contact options. Please feel free to contribute if you want to.
