Looksmart, Yahoo's main rival, also employs human editors to select and categorize web sites. LookSmart has partnered with AltaVista to be the extensive search engine that engages after a query of LookSmart's database. Critics note that the volunteer-nature of this type of service can lead to uneven subject coverage and potential bias. Use the subject listings or search by keyword or phrase to navigate the site. Easy to use, very browsable.
Annotations are a plus.
Like MetaCrawler, a favorite among searchers. Interesting is ixquick's use of a star rating system. One star is given for each search engine that placed a site in its top ten. The theory is that a site appearing in multiple top ten lists is likely to be relevant. Like Dogpile, ixquick tries to translate a search query into the syntax of each search engine.
