"First, you are investing time into a blog that is not on its own domain. You don't really own it - not sure how easy it would be to migrate. In many ways my blog is just waking up again, I took 9 months off - when I started blogging on this site I was pumping out 90 posts per month, I could have done much better spending my times in other ways, but I was looking to attract a specific audience which I couldn't attract with a landing page and squeeze. If you are looking to optimize a site, you need to do it for terms that set searched for and which you can monetize." - Andy Beard
