I've replaced UserLand's GoogleIt macro with liveTopics GoogleBug macro this morning. Both link the current post to a google query based on it.
UserLand's version bases hte query on the post's title. With liveTopics' version, the link is first based on the topics associated with the current post. If there are none, the title is used instead.
I inserted the following string in s l a m 's #itemTemplate file :
<%liveTopicsGoogleBug ( <%itemNum%> ) %>.
Simple enough.
Now what would be even cooler is a version that would actually query Google using its web service API, then insert a string of relevant links directly in the page.
