Feature request: "In response to" blogs
One of the things we haven't been able to achive with the blog system today, is discussion on topics. Most of the blogs are very technical and show you how to perform a certain task, nothing wrong with this, but it would be great to have some in-depth discussion by matter-experts on various topics.
I think you can facilitate this quite easily allowing a blog to be a response to another existing blog, and provide some method of showing the entire "discussion-thread" in an organized fashion (yes I stole the idea from YouTube, sue me!
The external link which exist today is not enough to facilitate this.
We could also have someone start with some controversial topics in order to spark the discussion:
"Why WD for Java is far superior to WD for ABAP"
"ESA - Been there, done that"
"ABAP coders, face the future of open languages"
"Java is the new Cobol" (Bring in DJ Adams for this one)
