Hi Tim, it's great to have you on the forums.
Is this a fair assessment?
+ Scooter still finds results for AV and AV is still a stand alone search engine in its own right.
+ FAST still finds results for AtW and AtW is a still a stand alone search engine in its own right.
However, new technologies developed by Yahoo! are likely to be single items shared by all the search engines owned by the company? Yahoo-MMCrawler is an example of this?
I think the new Yahoo results look really good. The web page summaries are especially fair.
