I like that you can customize your blog with different themes and layouts depending upon what kind of audience or niche market they are targeting for themselves. It's also easy to add social sharing features as it integrates well with other platforms such as Google+. The only thing about this site right now would be if there was more variety in terms of topics/niches being offered by those who post blogs within the network. Maybe something along the lines of how Tumblr works - have multiple options so people don't get bored easily when looking through them all (or just stick to one). We've been able to attract many readers from our website using the PostJoint blogging service, which has helped boost traffic significantly!
