Web 2.0 announcer just announced the release of the monetizer plugin for wordpress. The plugin can be used to display the top stories from social bookmarks – like Digg, netscape, delicious, etc. – for the tags you are interested in.
In addition to that web 2.0 announcer gives you 50% of the adsense advertisements, which is a good motivation to use the plugin 🙂
