Google says they are cracking down on spam. That would be nice as their results have not been very good recently. Almost every search has crappy results from the same sites such as ehow and yahoo answers. There's also the useless sites that want you to jump through hoops to get the answers to your questions and of course the answers are stolen.
Google says they're doing something about it but we'll see. They've gone too long with no real competition so they did just enough to get by or wasted time adding pointless "features" like the page preview thing.
I think I'm personally going to look at other search engines to see if it's any easier to find what I am actually searching for rather than the spammy crap.
