What have you done so far? Have you followed any of Darren's suggestions? (ProBlogger).
If I remember correctly, I believe I came across a discussion of yours on Darren's blog or the blog 'why my blog sucks' months ago (your idea of fluid posts was great).
CopyBlogger also has some excellent suggestions. As does Liz at Successful Blog. (I see you are a visitor at SB).
