Why does Blogspot Comment system suck?
1. The Word Verification feature is a total turn off for many readers. Although this feature is integrated by Blogger.com to prevent spam comments, many readers might find it too troublesome to verify themselves as human before being able to post a comment.
2. Readers are not allowed to include their own blog url and email along with the comments made.
3. To post a comment, a reader would redirected to another page(default Blogger comment page) that's not part of the original blog.

Say how would you like your blog comment system to look something like this:
Then head on over to IntenseDebate.com and get your blog an IntenseDebate Comment system. Once installed on your blog, your readers can post comments directly on your blog without the need to verify words or get directed to another page (somewhat similiar to the Wordpress comment system).
