Quick Links of the Day: Blekko, Silicon Valley History, and I hate your paper, and P!=NP

• Blekko - Daniel has a Blekko preview from the beta. See also Michael Arrington's post on SE Land. From Daniel's post:
  

  Rather, they are a way for users to “spin” their search results using a variety of filters. For example, [climate /liberal] and [climate /conservative] return very different results, because they are restricted to different sets of sites... In addition to providing a set of curated slashtags, Blekko allows users to define their own slashtags by specifying the sets of sites to be included.

  This is a very primitive means of creating mini vertical search engines. My first instinct is that slashtags remind me of Rollyo where you can "roll your own" by restricting search to a group of websites.
