All it requires is motivation and something to write about.
I treat it as an extended forum post that may or maynot have pics. Not everyone like long forum posts and others like greater detail, the blogs provide both.
Hmmm, maybe I wasn't being too clear.
My comparison of a blog post with the word "article" was only for showing the relative lenght of both. Like you said yourself, blogs are more for the somewhat longer posts than a typical forum thread. The
style in which you write a blog shouldn't (but can if you want to) be like a newspaper article, sorry for the confusion.
