In fact I used to use that service, but it’s a complete waste of space on your website, and most of the people displayed in there are not leaving comments anyway.

In this article, the author suggest the use of a plugin displaying top commenters or last commenters not only using their names, but also via gravatar service.

So, here is the plugin, he got the idea and I made it

Here is the list of features :

• Display whether Last commenters or top commenters
• Display user name (or not, via options)
• Display link to user’s website (or not, via options)
• Default gravatar
• Gravatar size

Download ZdCommentsWidget

Once you installed the plugin, just add it to your sidebar and choose your options. A tutorial and Documentation will be written in the next days.

It’s not yet available through WordPress extend, but it will be published today or tommorow. So you’ll be able to get automatic updates
