1) Bloggers write in the vain belief that our words and views may be of interest or use to others.
2) Bloggers write with unrealistic expectations of how many people are going to read our work.
3) Bloggers sometimes believe that their blogs will make them rich (hence the number of blogs on how to get rich through blogging.)
4) There are people who claim to be able to make your blog a success if you pay them. Their dark arts include Search Engine Optimisation (SEO), e-mail shots (spam) and Twitter (more spam).
On the other hand, here are two good reasons why blogging can be more like self-publishing:
1) No money needs to be paid to a third party.
2) If the writing is good enough and useful enough the blog will gradually attract an audience. If it is not, it won't. It would be the most brutal form of publishing if vanity was your driving motive.
As to the question of my driving motivation for writing this blog - I really haven't figured it out yet. I am certainly enthused by the possibilities of digital publishing. I believe the separation between different media and between different forms of writing are being re-cast at present, but can't yet see where we are heading. I believe big changes will come at the point where reading device for digital text become as pleasant as a book to use, robust enough to take to the beach and cheap enough to replace if you accidentally drop one in the bath (ie not yet but soon).
But at the root of my blogging habit is the same drive that animates all my writing - whether it be prose, poetry or screenplay - an intense curiosity about the world and a compulsive desire to communicate.
Many thanks for sharing the journey. Below is a graph showing the daily readership of this blog (the blue line) and the number of posts per week (the red line) going back to September last year. Sorry about the x-axis labelling. I still can't drive that Excel database package!
