I've got this idea:
A widget with Avatar Grids (or a list) from all people who comment on your blog. This would be very helpful because people like to read what a specific person wrote on other articles, how many people commented on the blog etc.
It's also good to connect people with each other !
A widget could look similar to the information on "Dashboard" - "Statistic" - "Comments".
The blog I need help with is prophetenschule.org.
