You can customize the features of this plugin available from WordPress the way you want, because it is created for your benefit. You will have the control over their appearance on your pages. You can set the plugin to appear on your home page or on other pages as well. Taking into account that this refers to all of your pages you must set the plugin to run only on the main page. I don’t know exactly if the plugin allows you to see the comments when you enter a certain category of articles. Probably, if there is not yet such functionality, it will be released soon in the future.
The plugin offers support for gravatars, so the users could use a picture, to enhance the conversation. You can adjust the layout of the plugin the way you want, with the help of the Macro commands. The comments may be ordered by their date or by post. You can set some categories to not have their comments displayed and so on. The plugin has been rewarded with 4 stars out of 5, so I think it would not cost you a thing, if you would try it.11
