I think people are rather blind? No?
Knowledge engine? Okay.
Search NFL scores, golf leaderboard, movie times, conversions, my ip, etc.
You don't need to leave Google. You don't need the websites, you just need Google.
On one hand you can question how they got that "knowledge" like the sports scores and did that knowledge cost money. As in are there deals with say the PGA that they get paid as compensation for the lost traffic. I know that personally I didn't need a website, I just read the information on Google. They are even excellent enough to have a "see more" link which expands the leaderboard so I could see where Tiger was at on the leaderboard. For me it was great. I'm sure the public would find this fantastic also. The big sites like the NFL or ESPN. Do you think they are sitting around and discussing a 10% drop in traffic?
If that's a knowledge engine then it's here. There is more of that now than a year ago and in the next year, I'm sure there will be more than this year.
It's possible that Google can hire it's own writers etc who can input this information rather than taking it and listing it. I think the newspapers were at one time having issues with Google? That's was nothing compared to what's really possible here.
You could ask what search queries are safe. That might be one strategy moving forward. It also might be a strategy to realize that what you have now is just a couple years short of being worthless. Sell now?
Again, I'm asking if that behavior is "knowledge" and the future. Learn the information from your site, paste it on yours, and therefore removing the middle man, you. Ouch!
