I agree with you. But maybe the aggregation isn't for more conversation (people like to do that within their trusted communities), but to enable better filtering. That is, you could have a rough total count of interest in a topic. Then you could label comments different things like "funny", "anecdote", "primary source", "trolling", etc. So if I just want to read the funniest comments, I could. If I wanted to get more context from on the ground, I could select "primary source" or whatever. Not sure why this isn't done already...I'm sure enough random commenters would categorize comments on their own to make it useful.
