Basically - I think the point of a blog (at the beginning) is not really to be lead gen for consulting gigs. Instead, it's a place to plant your flag on the internet and say "This is what I'm an expert in".
Eventually, that may lead to consulting leads - but at least at the start, it's really just a way to establish that you know what you're talking about. Either way - if you're thinking about doing consulting, I would highly recommend it.
