The new search engine Blekko has launched, so now seems like a good of a time as any to delve into the site and see what it's all about. Blekko was designed around the goal of eliminating spam results in internet search, via "slashtag technology" that narrows down the web into a select group of results. Specifically, the seven slashtag groups are: health, colleges, auto, personal finance, lyrics, recipes, and hotels. These are of course only the initial categories, with plans of expansion in the near future.
Blekko seeks to stand out against search big shots like Google and Bing, and here's an example of how: when a searcher types "health" into one of those engines, the results are a lot of low-quality content farms and spam. On the contrary, Blekko's results are only from high quality sites.
