Looking for a new way to search for information online? Try Blekko, a search engine featuring slashtag (/) searching. Slashtag categories are created by a group of initial users and guide searchers to trusted websites. For example, a Blekko search "headache/health" will return only health sites determined to be helpful by other users. Categories are rechecked with artificial intelligence software to ensure relevancy. Blekko sees slashtag searching as a way to bypass "junk" webpages and reach the most useful information quickly.
Blekko's examples of where slashtag searches come in handy include searches you can't do with keywords: global warming /conservative, ufos /paranormal, congress /humor and searches in categories that are otherwise heavily spammed: avoiding swine flu /health, iphone 4 reviews /techblogs, Aruba /travel.
Blekko's complete list of slashtags can be found here. You can also open an account with Blekko and create your own slashtags.
