Does that mean Blekko is just a nice-looking front end for the yahoo API?
I'm guessing the answer is no and the technology goes far deeper than that, but as an average user with an attention span nearing zero, it might be wise to make all this terminology a bit clearer. I don't want to have to distinguish between slashtag results, yahoo results, web results etc (and learn what they all mean) - why can't I just have results?
