Script Summary: Displays a message if the page has a WordPress.com recent comments widget. <i>This is only of interest to people who use WordPress.com as a blog host</i>
This is useful if you want to spend a bit of time commenting and connecting with other WordPress.com bloggers.
It notifies you about the Recent Comments widget because you may want to focus on blogs that have it since you'll get a link back to your site on every page for a little while.
Please do not use this to write spammy comments -- all WordPress.com blogs are protected by Akismet and you'll just end up blacklisting yourself.
