Using your blog to build a prospect list would be perfect. Just make sure that the content that you are using to catch their interest is not only compelling, but truthful as well. After all, captivating the interest of others without gaining their trust is useless to say the least.
Same as insight, I would suggest that you get a blog running and start building relationships first. Once you have a faithful reader base, your promotions will be much more successful than if you start promoting right away. People hate being sold to by strangers! :x
