The WP Latest Post Blogroll plugin improves the static blogroll by showing new and different links with each new post on your favorite sites. It fetches the most recent post title for each blog listed in the blogroll. The blogroll is then presented as a list of links to these latest blog posts. Instead of a static list of links to the blogroll sites, the links list appears differently with every blog post published.
WP Latest Post Blogroll updates your links list with the last post title for each link. With a dynamic blogroll your site will always be current with no more effort from you. All you have to do is install and activate the plugin. There are no options to fiddle with!

Blogroll Fun uses a subscription to a free service that allows it to easily determine the last update time and the last post for all of the links in your blogroll without slowing down the loading time of your blog. It allows you to choose if you want to display this information in your blogroll or not. It simply replaces the standard wordpress link widget while providing additional functionality.
Blogroll Fun can be compared to the feed reading blogroll. However, unlike feed reading blogroll the last post information is sent to your blog and stored with your blogroll. It does not rely on your visitors to load this information, or any javascript tricks.
Settings can be updated by going to manage, widgets, then edit on the links widget.
Currently, no ads are being delivered through this plugin.
