Yeah I would be interested to know aswell. I have been content with using a listing type for a blog on my site, with abit of css to style blocks etc to get a different look, and I am happy with it.
But I realised a blog is going to be big part of my website now so going forward I am not sure wether a dedicated blog would be more beneficial.
But with my current setup I can add multiple listing blocks for different things etc where as using the bridge its just one block of posts so I believe.
