One of the reasons for using vB4's CMS is the integration with the blog. Since most Wordpress blogs allow comments without registration, they often make it easy for visitors to comment. With vB's current implementation, comments get placed in the CMS and in vBCMS Comments (or a forum category of your choice). My thinking is that you'd want to promote your articles (and comments) within your forums. I currently have comments accessible from both the front end CMS and the forums. Essentially, I've got duplication.
I wondering what other sites are doing and what many feel is the best practice for increasing the number of comments and making for more active discussions throughout a vB4 site.
