There is still a lot of misunderstanding of what it's like to participate in a community of blogs. It really turns out that the functional capability of the two are fairly similar and you could likely create a very similar kind of conversation in each. However, the two have a tendancy to have different norms/culture emerge.
One thing I have experience myself is that a blog has been a much better personal learning tool than participating in discussion forums. It has also been a much better way for me to connect and build a relationship with other people (bloggers).
