I have a FB page too. The key is to market the FB page as a bit 'behind the scenes' if you see what I mean? Ask questions, make comments, post links, share interesting posts and statuses, make it all a bit silly and fun, and above all keep it interactive.
If someone likes you, check to see if they have a page, and like back.
If someone comments, reply back. If someone likes a post, thank them.
If you write serious stuff on your blog, link it up, and add relevant links. Don't just make it about your blog though, add relevant links etc from other places like newspapers. Encourage people to participate.
This will mean that when you add a new blog post, it'll show up on people's walls and you are more likely to get hits from it. I get a fair amount of hits from my friends and family, but there are a lot of strangers out there who like my page, and interact with me on it.
