I think it will be more relevant if the Recent Comments widget will not include the comments made by the blog authors.
Just imagine how the widget will look like if I replied on all the comments in 1 bulk (because of lack of time to do otherwise), the list would purely contain my gravatar profile which I don't think is necessarily pleasing to anyone.
I guess you can add an option if blog authors would want to appear in the widget box or not. Since a couple would probably prefer seeing themselves in the widget, especially if there are multiple authors in a blog.
The blog I need help with is theeagertraveller.com.
