A couple weeks ago, we noted that Automattic was testing out a new Top Author stat area on the Site Stats page found on WordPress.com blogs. Today, they&'ve rolled out the feature with a couple little bonuses.

First of all, the widget itself has been prettied-up quite a bit from the one we shared. You&'ll now see author icons next to the author names. More importantly, you&'ll see a plus sign, which, when clicked, presents a drop down that shows you exactly what stories by that author are brining in traffic on any given day. WordPress.com also removed the number of posts area, after that caused some confusion. &''the top spot is not about who wrote the most posts, it‚a4‚¬‚a4„s about which author wrote the posts that got the most visits,&'' they note.

WordPress.com says that they liked the new icon and drop down so much, that they&'ve also added it to the Referrers box as well. The result is a simple way to see things like which Twitter account is sending the most traffic your way. Pretty nifty.

WordPress.com says the stats upgrade is available for all blogs on WordPress.com and it will 'automatically 'appear if your blog has two or more authors with traffic on their posts. Automattic also notes that these features will be coming to the Stats plugin for self-hosted WordPress blogs shortly.
