One of the main reason for writing a blog is to attract readership. Otherwise you could as well be doing some exercise or have a beer watching your favorite TV show.
The readership is especially useful if you have a message to promote (political, social, business, health...) For instance, I quite often mention my Snap! Websites system, obviously since I'm writing about it! Yet, even though it is toward promoting Snap!, you can get a lot of valuable information from my posts, and, of course, I expect you to remember the name Snap!...
Good. Now... How can I remember all the important things to write a post?
