Lijit can improve your blog searching like FeedBurner can improve your feed.
I’m outsourcing my blog search to Lijit because it sounds cool. You can still use the plain old boring built-in WordPress search. Or you can use Lijit’s funky turbo-search (not what they call it).
Of course, sometimes I wonder why I even care what my blog looks like, since the vast majority of those who read this blog do so via a feed reader, not via a web browser.
