Blackle is a crap site to being with, so you making a clone equals to an ever more crap site. Your logo also looks like it is from 1999. Overall, you should just move on dude and stop dreaming that your site will go viral... because it won't since it is merely a customized Google search.
I think it is pretty clear. Nearly 75% of people have voted under 5. How much clearer do you want it? Look, big businesses all over the world do surveys of their customers opinions. When they get the results they don't ask more people to vote to try and change the result to what they want. They take action on what the results show them. If the results show that the customers don't like what they see, this makes them change something so that the customers do like it. It is pointless doing a poll and waiting for the results that you want to see. It doesn't help you make a better site.
It is .. Both use the Google API .. The only difference between the two is that the API key's are different.
Well not everyone on the site is going to vote. That is why the poll works on percentages. As you can see, the results show that most people don't like it. The trend has stayed that way since you started the poll and it hasn't changed.
