Personally I prefer to see everything with less effort.
So a forum post with all the content in the actual forum post will for me, trump a forum post that links to a blog with all the content on the blog.
I am that lazy/busy.
So content here will be more likely to be seen by me than content I have to click on to get to.
On a similar note, I am unlikely to click on a link to a blog that has no teaser pics in the forum to tempt me.
Just a link rarely swings it for me.
A forum post inviting people to go to a blog is an advert for that blog, and for me adverts work better with images.
I hope that makes sense, I have not had breakfast yet and am running on coffee alone..
