Gurunet, the useful research database/answer engine, has been making plenty of news lately.
Last week, we learned that some of GuruNet content is available via a9. A week earlier, word that a beta version of their search app (ver. 5.2) offers desktop search capabilities. Today, Gurunet released a new toolbar (ver. 2.0, IE only) that contains a pop-up blocker, a page translation tool, and Alt Click support.
Bing is testing a new 'One Last Step' human verification screen before displaying search results, part of a broader trend of search engines adding anti-bot measures.
