I would love to get some feedback and thoughts on (a) the best approaches for encouraging commenting and participation on a blog, and (b) which commenting platforms do you use.
For (a), I would love to learn which approaches you have found to be effective in encourage repeat participation. For example, do you include top/recent comments in the sidebar, do you trigger comments in the posts, etc.
For (b), which platform do you use? Do you use native CMS comments (e.g. Wordpress, Drupal), or a dedicated comment platform such as Disqus?
