More on Blogging and Community Issues

I just saw that TechCrunch added a forum to their blog. This relates closely to the discussion going on around blogs, discussion forums, communities, etc.:

• Blogs and Community – launching a new paradigm for online community?
• eLearning Discussions - An Attempt at Better Discussions in the Blogosphere
• Move from Discussion Groups to World of Blogs?
• Top Ten Reasons To Blog and Top Ten Not to Blog
• I found it inside my blog reader!
• Blogs vs. Discussion Groups or Mis-Understanding Blog Reading and ...

Many of the people posting into the TechCrunch forum are asking some familiar sounding questions: Why would a blog need a forum? How does the forum relate to comments?

And this is a case where it's only one blog. In our world, there are many blogs. So, it's even more complicated of an issue.
