i understand fully, what you fail to do is provide a set of posting rules, i know that they are personal blogs, but you have to say what is acceptable and not.
i.e. can i post 20,000 porn pics in my personal boonex blog? no i bet not. yet you have no real rules or guidelines for people to follow, so everyone is posting what they want where they want.
Main purpose of Forum is discussion/collaboration/distributed input.
Main purpose of Blog is to provide accounts of events, news and information.
Comments are killing that difference... So if you want to understand the difference better, just think of "forums" and "blogs without comments".
