The front-page here is just to explain what it is. Use-case:you are sharing a url that you know will be the first search result for a simple word, so you just share <a href="http://bloo.tk/simple+word" rel="nofollow">http://bloo.tk/simple+word</a>
I've been using <a href="http://www.google.com/search?q=%s&btnI=Im+Feeling+Lucky" rel="nofollow">http://www.google.com/search?q=%s&btnI=Im+Feeling+Lucky</a> as a search engine in chrome.
