Cuil, who have seen their traffic tumble into free fall since their much-hyped (but severely botched) launch, have suffered another blow today, as TechCrunch reports that VP Product, Louis Monier, has quit the company:

“Louis Monier, Cuil’s VP Product, quietly resigned from the newly launched search engine last week, we’ve heard from a reliable source. “

Monier was one of the big draws for the simply stunning amount of PR that Cuil generated – he was hired  away from Google last year in a major coup for the young start up, but is even more well known as the Father of AltaVista, everyone’s favorite search engine before Google came along. His departure is thought to be related to the path Cuil should take.

With a resume which also includes stints at Xerox PARC,  Ebay and Google, Monier is regarded as one of the big names in tech and search, so the blow will be a huge one for Cuil. After all, he left Alta Vista, then the #1 search engine, after a similar disagreement over the move from straight search to becoming a portal (how 1999!)..and look what happened to AV after that.
