How can a search engine possibly be more appealing than Google? In Blekko's case, filtering out spam, "demand" results, and automatically editing certain marketing-saturated results is their killer app. It's definitely worth a look if you're running across dishearteningly spammy results.
Blekko does some automatic editing on certain spam-flooded search areas, like cars, health, hotels, and song lyrics. It also harnesses some of the power of other focused search engines, such as Bing's travel tools. But Blekko's main weapon against craptacular results are its "slashtags". Think of them as powerful, category-defining tags, kind of like the tags we use around this joint. Search for "android /reviews," and you get sites narrowed down to those with real reviews. Enter "android /science," and you'll see mostly links related to the study of human-like robots — though Google's smartphone system creeps in there, of course. You can search "climate change /liberal" to see left-leaning results on the impact of humans on global conditions, or "climate change /conservative" for the opposite.
Blekko is a free service, though you can create an account to save certain preferences and get credit for creating your own slashtags.
