Why don't the comment sections of most blogs have a "reply" feature?
I'm not asking because I necessarily feel there should be one but rather as a website developer, I'm curious if this is something I should incorporate into my company site's blog.
The other day, someone in my company had mentioned it would be great if we had a "reply" link on each comment, similar to how youtube set thier comments section up. I didn't give a yes or no answer because I honestly wasn't sure if there's a legitimate reason why most blogs don't do replies.
Is there perhaps a concern replies lead to too much back-and-forth arguing? Just curious.
