Richard Webster of Writers in Oxford on blogs
“But they do demand something which not all writers possess – time and regular habits. Running a blog is rather like running a shop. If you don’t open regularly you will end up with no customers. Of course you don’t have to be there from 9 to 5. But unless you post at least every couple of weeks (and preferably every two or three days) your readers may desert you. Many people start blogging with noble intentions but find they simply cannot find time to continue. As a result cyberspace is littered with forgotten blogs which orbit the earth like abandoned spacecraft whose last log entry reads more like a fading note from history than a recent update.”
But just as a failed writing career is better than none at all, (ask Helene Hanff), stabs at a blog read by just a few is better than none at all, because the greatest beneficiary of a blog is the writer herself!
