This was a good post. #2 was the most annoying to me. I noticed that the main problem has to do with Chrome remembering your user behavior which affects your results.
I agree. I use it. Sometimes good, sometimes crap, but I use it. This is getting annoying though... Everyone lately has been just spouting what should and should not be in google's results based on what they consider good content. Come on.
I got to be honest. Blocking sites doesn't seem to be working that well for you guys.
Look at this search - "how to get pregnant" - that exact phrase gets 550K searches on google a month. My wife and I did this search last week actually.
Blekko's top 3 results are 1. get-pregnant-guide.com which is an affiliate site that points to pregnancymiracle.com - one of those crappy ebook sites where they have a bunch of testimonials and ask for you to pay $39.95 for their guide, 2. a digg post that has 1 digg which points to a hubpages article that no longer exists, 3. purelyfitness.com/how-to-get-pregnant which is also an affiliate site that points to pregnancymiracle.com.
Google's top sites are the mayoclinic.com, mahalo.com, and howtogetpregnant.net. The least useful to me was howtogetpregnant.net, but they still gave a decent amount free advice. I actually found Mahalo to be the most informative which is blocked from your results. I find Calacanis just as annoying as everyone else, but this page was more beneficial to me than even the mayoclinic.
