Do you have a concept?
Usually this is the first question I give people who ask me to do them a blog. What do you want to write about? Where do you see your blog in a half year, in one year? I tell them not to go a strict business way, but all the blogs started by some friends without a aim got quite empty after a while.
You need a concept and it can be only as small as mine: Writing an English blog to improve my language. And my wallet maybe too.
I do web design. I ask the people what they want to write about because i think a web design should have something out of the author and something from the theme it will be about. But how to design a for a blog just written to write? I want to improve my language without thinking about some special topic. I will write what is in my mind. Because of that this blog looks quite boring. This is the concept.
