RECENTLY THE FEATURE 'Embedded Comments' has been made available for all Blogger users.
This allows users to reply from the post, and what I especially like about this is its 'threading' ability. That is to say, if someone leaves a comment, you can reply directly to that comment right underneath, so the conversation on a particular comment stays together... it keep the like-conversation connected. (You'll see how it works in my comment area below).
It's a simple process to do:
1. Go to your Settings.
2. Select Posts and Comments.
3. Under Comments Location*, choose EMBEDDED
4. Ensure the Allow Blog Feed is set to FULL.
*Note: If you click on the wee question mark beside Comments Location, the following comment comes up: "Embedded will allow users to reply from the post; Full page and Popup window will take them to a new page. Note: Selecting Hide does not delete existing comments. You can show them at any time by selecting another option."
Hope that works for you. For more info on this, you can check out the the link to Ask the Blogster.
